Sunlight is a portion of the electromagnetic radiation given off by the Sun , in particular infrared , visible , and ultraviolet light. On Earth , sunlight is scattered and filtered through Earth's atmosphere as daylight when the Sun is above the horizon . When direct solar radiation is not blocked by clouds , it is experienced as sunshine , a combination of bright light and radiant heat (atmospheric). When blocked by clouds or reflected off other objects , sunlight is diffused . Sources estimate a global average of between 164 watts to 340 watts per square meter over a 24-hour day; this figure is estimated by NASA to be about a quarter of Earth's average total solar irradiance .

86-567: Koreatown, Queens ( Korean :  롱 아일랜드 코리아타운 ), in the New York City borough of Queens , is one of the largest and fastest-growing ethnic Korean enclaves outside Korea . It is largely oriented around Northern Boulevard . The core of this Koreatown originated in the Flushing neighborhood of the New York City borough of Queens . This Koreatown has continued to expand rapidly eastward alongside Northern Boulevard through

172-503: A charged particle would take between 10,000 and 170,000 years to get to the surface. Sunlight is a key factor in photosynthesis , the process used by plants and other autotrophic organisms to convert light energy , normally from the Sun, into chemical energy that can be used to synthesize carbohydrates and fuel the organisms' activities. Daylighting is the natural lighting of interior spaces by admitting sunlight. Solar irradiance

258-641: A foreign language ) is also generated by longstanding alliances, military involvement, and diplomacy, such as between South Korea–United States and China–North Korea since the end of World War II and the Korean War . Along with other languages such as Chinese and Arabic , Korean is ranked at the top difficulty level for English speakers by the United States Department of Defense . Modern Korean descends from Middle Korean , which in turn descends from Old Korean , which descends from

344-484: A Korean influence on Khitan. The hypothesis that Korean could be related to Japanese has had some supporters due to some overlap in vocabulary and similar grammatical features that have been elaborated upon by such researchers as Samuel E. Martin and Roy Andrew Miller . Sergei Starostin (1991) found about 25% of potential cognates in the Japanese–Korean 100-word Swadesh list . Some linguists concerned with

430-654: A Koreatown was conceived in Flushing. As the community grew in socioeconomic status and population, Koreans moved eastward along Northern Boulevard, buying homes in more affluent and less crowded Queens neighborhoods, and into the adjacent Nassau County , by the early 21st century. This expansion has led to the creation of an American Meokjagolmok , or Korean Restaurant Street , around the Long Island Rail Road station in Murray Hill, Queens, exuding

516-480: A core vowel. The IPA symbol ⟨ ◌͈ ⟩ ( U+0348 ◌͈ COMBINING DOUBLE VERTICAL LINE BELOW ) is used to denote the tensed consonants /p͈/, /t͈/, /k͈/, /t͡ɕ͈/, /s͈/ . Its official use in the extensions to the IPA is for "strong" articulation, but is used in the literature for faucalized voice . The Korean consonants also have elements of stiff voice , but it is not yet known how typical this

602-584: A day, the highest amount of sunlight on a horizontal surface occurs in January at the South Pole (see insolation ). Dividing the irradiance of 1,050 W/m by the size of the Sun's disk in steradians gives an average radiance of 15.4 MW per square metre per steradian. (However, the radiance at the center of the sun's disk is somewhat higher than the average over the whole disk due to limb darkening .) Multiplying this by π gives an upper limit to

688-545: A later founder effect diminished the internal variety of both language families. Since the establishment of two independent governments, North–South differences have developed in standard Korean, including variations in pronunciation and vocabulary chosen. However, these minor differences can be found in any of the Korean dialects , which are still largely mutually intelligible . The Chinese language , written with Chinese characters and read with Sino-Xenic pronunciations ,

774-562: A less clear, and probably more complicated fashion, with Earth's climate responses than earlier assumed, fueling broad avenues of new research in "the connection of the Sun and stratosphere, troposphere, biosphere, ocean, and Earth's climate". The spectrum of surface illumination depends upon solar elevation due to atmospheric effects, with the blue spectral component dominating during twilight before and after sunrise and sunset, respectively, and red dominating during sunrise and sunset. These effects are apparent in natural light photography where

860-428: A nearly perfect circle, and at other times stretching out to an orbital eccentricity of 5% (currently 1.67%). As the orbital eccentricity changes, the average distance from the Sun (the semimajor axis does not significantly vary, and so the total insolation over a year remains almost constant due to Kepler's second law , where A {\displaystyle A} is the "areal velocity" invariant. That is,

946-463: A number of states in the world. For many people with light skin, one purpose for sunbathing is to darken one's skin color (get a sun tan), as this is considered in some cultures to be attractive, associated with outdoor activity, vacations/holidays , and health. Some people prefer naked sunbathing so that an "all-over" or "even" tan can be obtained, sometimes as part of a specific lifestyle. Controlled heliotherapy , or sunbathing, has been used as

1032-574: A possible relationship.) Hudson & Robbeets (2020) suggested that there are traces of a pre- Nivkh substratum in Korean. According to the hypothesis, ancestral varieties of Nivkh (also known as Amuric ) were once distributed on the Korean Peninsula before the arrival of Koreanic speakers. Korean syllable structure is (C)(G)V(C), consisting of an optional onset consonant, glide /j, w, ɰ/ and final coda /p, t, k, m, n, ŋ, l/ surrounding

1118-537: A risk factor for skin cancer, "sun avoidance may carry more of a cost than benefit for over-all good health". A study found that there is no evidence that UV reduces lifespan in contrast to other risk factors like smoking, alcohol and high blood pressure. Elevated solar UV -B doses increase the frequency of DNA recombination in Arabidopsis thaliana and tobacco ( Nicotiana tabacum ) plants. These increases are accompanied by strong induction of an enzyme with

1204-418: A room less than fluorescent or incandescent lighting. Multiplying the figure of 1,050 watts per square meter by 93 lumens per watt indicates that bright sunlight provides an illuminance of approximately 98,000 lux ( lumens per square meter) on a perpendicular surface at sea level. The illumination of a horizontal surface will be considerably less than this if the Sun is not very high in the sky. Averaged over

1290-479: A treatment for psoriasis and other maladies. Skin tanning is achieved by an increase in the dark pigment inside skin cells called melanocytes , and is an automatic response mechanism of the body to sufficient exposure to ultraviolet radiation from the Sun or from artificial sunlamps. Thus, the tan gradually disappears with time, when one is no longer exposed to these sources. The ultraviolet radiation in sunlight has both positive and negative health effects, as it

1376-490: Is a measure of flux density , is the amount of incoming solar electromagnetic radiation per unit area that would be incident on a plane perpendicular to the rays, at a distance of one astronomical unit (AU) (roughly the mean distance from the Sun to Earth). The "solar constant" includes all types of solar radiation, not just the visible light . Its average value was thought to be approximately 1,366 W/m , varying slightly with solar activity , but recent recalibrations of

1462-641: Is also spoken by Sakhalin Koreans in parts of Sakhalin , the Russian island just north of Japan, and by the Koryo-saram in parts of Central Asia . The language has a few extinct relatives which—along with the Jeju language (Jejuan) of Jeju Island and Korean itself—form the compact Koreanic language family . Even so, Jejuan and Korean are not mutually intelligible . The linguistic homeland of Korean

1548-410: Is ample sunlight. Some common places for sunbathing include beaches , open air swimming pools , parks , gardens , and sidewalk cafes . Sunbathers typically wear limited amounts of clothing or some simply go nude . For some, an alternative to sunbathing is the use of a sunbed that generates ultraviolet light and can be used indoors regardless of weather conditions. Tanning beds have been banned in

1634-656: Is an agglutinative language . The Korean language is traditionally considered to have nine parts of speech . Modifiers generally precede the modified words, and in the case of verb modifiers, can be serially appended. The sentence structure or basic form of a Korean sentence is subject–object–verb (SOV), but the verb is the only required and immovable element and word order is highly flexible, as in many other agglutinative languages.

1720-437: Is both a principal source of vitamin D 3 and a mutagen . A dietary supplement can supply vitamin D without this mutagenic effect, but bypasses natural mechanisms that would prevent overdoses of vitamin D generated internally from sunlight. Vitamin D has a wide range of positive health effects, which include strengthening bones and possibly inhibiting the growth of some cancers. Sun exposure has also been associated with

1806-511: Is closer to a near-open central vowel ( [ɐ] ), though ⟨a⟩ is still used for tradition. Grammatical morphemes may change shape depending on the preceding sounds. Examples include -eun/-neun ( -은/-는 ) and -i/-ga ( -이/-가 ). Sometimes sounds may be inserted instead. Examples include -eul/-reul ( -을/-를 ), -euro/-ro ( -으로/-로 ), -eseo/-seo ( -에서/-서 ), -ideunji/-deunji ( -이든지/-든지 ) and -iya/-ya ( -이야/-야 ). Some verbs may also change shape morphophonemically. Korean

The solar illuminance constant ( E sc ), is equal to 128×10   lux . The direct normal illuminance ( E dn ), corrected for the attenuating effects of the atmosphere is given by: where c is the atmospheric extinction and m

1978-569: Is fueled by light from the Sun. Most autotrophs , such as plants, use the energy of sunlight, combined with carbon dioxide and water, to produce simple sugars—a process known as photosynthesis . These sugars are then used as building-blocks and in other synthetic pathways that allow the organism to grow. Heterotrophs , such as animals, use light from the Sun indirectly by consuming the products of autotrophs, either by consuming autotrophs, by consuming their products, or by consuming other heterotrophs. The sugars and other molecular components produced by

2064-399: Is mainly reserved for specific circumstances such as newspapers, scholarly papers and disambiguation. Today Hanja is largely unused in everyday life but is still important for historical and linguistic studies. The Korean names for the language are based on the names for Korea used in both South Korea and North Korea. The English word "Korean" is derived from Goryeo , which is thought to be

They are produced with a partially constricted glottis and additional subglottal pressure in addition to tense vocal tract walls, laryngeal lowering, or other expansion of the larynx. /s/ is aspirated [sʰ] and becomes an alveolo-palatal [ɕʰ] before [j] or [i] for most speakers (but see North–South differences in the Korean language ). This occurs with

2322-533: Is readily available in Koreatown. Korean language Korean ( South Korean : 한국어 , Hanguk-eo ; North Korean : 조선어 , Chosŏnŏ ) is the native language for about 81 million people, mostly of Korean descent. It is the national language of both North Korea and South Korea . Beyond Korea, the language is recognized as a minority language in parts of China , namely Jilin , and specifically Yanbian Prefecture , and Changbai County . It

2408-544: Is suggested to be somewhere in contemporary Manchuria . The hierarchy of the society from which the language originates deeply influences the language, leading to a system of speech levels and honorifics indicative of the formality of any given situation. Modern Korean is written in the Korean script ( 한글 ; Hangeul in South Korea, 조선글 ; Chosŏn'gŭl in North Korea), a system developed during

2494-618: Is the 12th busiest subway station in the subway system. The intersection of Main Street and Roosevelt Avenue, at the western end of Koreatown, is the third-busiest intersection in New York City, behind only Times Square and Herald Square in the borough of Manhattan . Numerous other public bus and rail connections also serve Koreatown at the Main Street/Roosevelt Avenue intersection, including 22 bus lines, and

2580-483: Is the relative optical airmass . The atmospheric extinction brings the number of lux down to around 100,000 lux. The total amount of energy received at ground level from the Sun at the zenith depends on the distance to the Sun and thus on the time of year. It is about 3.3% higher than average in January and 3.3% lower in July (see below). If the extraterrestrial solar radiation is 1,367 watts per square meter (the value when

2666-415: Is the solar energy available from sunlight. Researchers can measure the intensity of sunlight using a sunshine recorder , pyranometer , or pyrheliometer . To calculate the amount of sunlight reaching the ground, both the eccentricity of Earth's elliptic orbit and the attenuation by Earth's atmosphere have to be taken into account. The extraterrestrial solar illuminance ( E ext ), corrected for

In the context of growing Korean nationalism in the 19th century, the Gabo Reform of 1894 abolished the Confucian examinations and decreed that government documents would be issued in Hangul instead of literary Chinese. Some newspapers were published entirely in Hangul, but other publications used Korean mixed script , with Hanja for Sino-Korean vocabulary and Hangul for other elements. North Korea abolished Hanja in writing in 1949, but continues to teach them in schools. Their usage in South Korea

In prehistory , humans began to further extend this process by putting plant and animal materials to other uses. They used animal skins for warmth, for example, or wooden weapons to hunt. These skills allowed humans to harvest more of

4042-455: The beginnings of words. /l/ becomes alveolar flap [ɾ] between vowels, and [l] or [ɭ] at the end of a syllable or next to another /l/ . A written syllable-final ' ㄹ ', when followed by a vowel or a glide ( i.e. , when the next character starts with ' ㅇ '), migrates to the next syllable and thus becomes [ɾ] . Traditionally, /l/ was disallowed at the beginning of a word. It disappeared before [j] , and otherwise became /n/ . However,

Sunshine is often blocked from entering buildings through the use of walls , window blinds , awnings , shutters , curtains , or nearby shade trees . Sunshine exposure is needed biologically for the production of Vitamin D in

4214-445: The change in solar energy in summer and winter. For example, at latitudes of 65 degrees, this can vary by more than 25% as a result of Earth's orbital variation. Because changes in winter and summer tend to offset, the change in the annual average insolation at any given location is near zero, but the redistribution of energy between summer and winter does strongly affect the intensity of seasonal cycles. Such changes associated with

4300-881: The core of the Sun is via the very weakly interacting neutrinos . Although the solar corona is a source of extreme ultraviolet and X-ray radiation, these rays make up only a very small amount of the power output of the Sun (see spectrum at right). The spectrum of nearly all solar electromagnetic radiation striking the Earth's atmosphere spans a range of 100  nm to about 1  mm (1,000,000 nm). This band of significant radiation power can be divided into five regions in increasing order of wavelengths : Tables of direct solar radiation on various slopes from 0 to 60 degrees north latitude, in calories per square centimetre, issued in 1972 and published by Pacific Northwest Forest and Range Experiment Station, Forest Service, U.S. Department of Agriculture, Portland, Oregon, USA, appear on

4386-466: The development of this Koreatown has led to the creation of an American Meokjagolmok , or Korean Restaurant Street , around the Long Island Rail Road station in Murray Hill, Queens, exuding the ambiance of Seoul itself. Korean Chinese cuisine is also available in Koreatown. Korean and English are both spoken prevalently in Koreatown. Retail signs employing the Hangul alphabet are ubiquitous. As

4472-443: The direct radiation is not blocked by clouds, it is experienced as sunshine . The warming of the ground (and other objects) depends on the absorption of the electromagnetic radiation in the form of heat . The amount of radiation intercepted by a planetary body varies inversely with the square of the distance between the star and the planet. Earth's orbit and obliquity change with time (over thousands of years), sometimes forming

4558-410: The elliptic orbit by using the day number of the year (dn), is given to a good approximation by where dn=1 on January 1; dn=32 on February 1; dn=59 on March 1 (except on leap years, where dn=60), etc. In this formula dn–3 is used, because in modern times Earth's perihelion , the closest approach to the Sun and, therefore, the maximum E ext occurs around January 3 each year.

Korean people in the former USSR refer to themselves as Koryo-saram or Koryo-in (literally, " Koryo/Goryeo persons"), and call the language Koryo-mal' . Some older English sources also use the spelling "Corea" to refer to the nation, and its inflected form for the language, culture and people, "Korea" becoming more popular in

4730-479: The inflow of western loanwords changed the trend, and now word-initial /l/ (mostly from English loanwords) are pronounced as a free variation of either [ɾ] or [l] . All obstruents (plosives, affricates, fricatives) at the end of a word are pronounced with no audible release , [p̚, t̚, k̚] . Plosive sounds /p, t, k/ become nasals [m, n, ŋ] before nasal sounds. Hangul spelling does not reflect these assimilatory pronunciation rules, but rather maintains

4816-435: The integration over the orbital period (also invariant) is a constant. If we assume the solar radiation power  P as a constant over time and the solar irradiation given by the inverse-square law , we obtain also the average insolation as a constant. However, the seasonal and latitudinal distribution and intensity of solar radiation received at Earth's surface does vary. The effect of Sun angle on climate results in

4902-503: The irradiance which can be focused on a surface using mirrors: 48.5 MW/m . The spectrum of the Sun's solar radiation can be compared to that of a black body with a temperature of about 5,800  K (see graph). The Sun emits EM radiation across most of the electromagnetic spectrum . Although the radiation created in the solar core consists mostly of x rays , internal absorption and thermalization convert these super-high-energy photons to lower-energy photons before they reach

4988-408: The issue between Japanese and Korean, including Alexander Vovin, have argued that the indicated similarities are not due to any genetic relationship , but rather to a sprachbund effect and heavy borrowing, especially from Ancient Korean into Western Old Japanese . A good example might be Middle Korean sàm and Japanese asá , meaning " hemp ". This word seems to be a cognate, but although it

5074-639: The language is most often called Joseon-mal , or more formally, Joseon-o . This is taken from the North Korean name for Korea (Joseon), a name retained from the Joseon dynasty until the proclamation of the Korean Empire , which in turn was annexed by the Empire of Japan . In mainland China , following the establishment of diplomatic relations with South Korea in 1992, the term Cháoxiǎnyǔ or

5160-455: The late 1800s. In South Korea the Korean language is referred to by many names including hanguk-eo ("Korean language"), hanguk-mal ("Korean speech") and uri-mal ("our language"); " hanguk " is taken from the name of the Korean Empire ( 대한제국 ; 大韓帝國 ; Daehan Jeguk ). The " han " ( 韓 ) in Hanguk and Daehan Jeguk is derived from Samhan , in reference to

5246-458: The light within a specific sensitivity range. Many animals (including humans) have a sensitivity range of approximately 400–700 nm, and given optimal conditions the absorption and scattering by Earth's atmosphere produces illumination that approximates an equal-energy illuminant for most of this range. The useful range for color vision in humans, for example, is approximately 450–650 nm. Aside from effects that arise at sunset and sunrise,

These studies show that in addition to the solar irradiance variation with the solar cycle (the (Schwabe) cycle), the solar activity varies with longer cycles, such as the proposed 88 year (Gleisberg cycle), 208 year (DeVries cycle) and 1,000 year (Eddy cycle). The solar constant

5504-410: The photosphere have different temperatures, and this partially explains the deviations from a black-body spectrum. There is also a flux of gamma rays from the quiescent sun, obeying a power law between 0.5 and 2.6 TeV . Some gamma rays are caused by cosmic rays interacting with the solar atmosphere, but this does not explain these findings. The only direct signature of the nuclear processes in

5590-407: The plaintiff. According to The New York Times , a " Kimchi Belt " stretches along Northern Boulevard and the Long Island Rail Road tracks, from Flushing into Nassau County. However, a prominent Korean food chef stated that "Queens is the closest you can come to authentic Korean food." Koreatown features numerous restaurants that serve both traditional and/or regional Korean cuisine . As noted above,

5676-592: The population has grown, Koreatown has concomitantly gained increasing economic and political clout. Upscale Korean-owned shopping centers continue to open along the Northern Boulevard corridor. In November 2012, Ron Kim was elected as the first Korean American to the New York State Legislature , representing the 40th district . A significant array of social services toward assisting recent as well as established Korean immigrants,

5762-515: The population was illiterate. In the 15th century King Sejong the Great personally developed an alphabetic featural writing system , known today as Hangul , to promote literacy among the common people. Introduced in the document Hunminjeongeum , it was called eonmun ('colloquial script') and quickly spread nationwide to increase literacy in Korea. The Korean alphabet was denounced by

5848-401: The principal source of illumination is sunlight as mediated by the atmosphere. While the color of the sky is usually determined by Rayleigh scattering , an exception occurs at sunset and twilight. "Preferential absorption of sunlight by ozone over long horizon paths gives the zenith sky its blueness when the sun is near the horizon". The Sun may be said to illuminate , which is a measure of

5934-443: The redistribution of solar energy are considered a likely cause for the coming and going of recent ice ages (see: Milankovitch cycles ). Space-based observations of solar irradiance started in 1978. These measurements show that the solar constant is not constant. It varies on many time scales, including the 11-year sunspot solar cycle. When going further back in time, one has to rely on irradiance reconstructions, using sunspots for

6020-581: The relevant satellite observations indicate a value closer to 1,361 W/m is more realistic. Since 1978, a series of overlapping NASA and ESA satellite experiments have measured total solar irradiance (TSI) – the amount of solar radiation received at the top of Earth's atmosphere – as 1.365 kilo⁠watts per square meter (kW/m ). TSI observations continue with the ACRIMSAT /ACRIM3, SOHO /VIRGO and SORCE /TIM satellite experiments. Observations have revealed variation of TSI on many timescales, including

6106-500: The remnants of ancient plant and animal matter, formed using energy from sunlight and then trapped within Earth for millions of years. The effect of sunlight is relevant to painting , evidenced for instance in works of Édouard Manet and Claude Monet on outdoor scenes and landscapes. Many people find direct sunlight to be too bright for comfort; indeed, looking directly at the Sun can cause long-term vision damage. To compensate for

6192-592: The second-largest population of ethnic Koreans outside Korea. Korean Air and Asiana Airlines provide non-stop flights from Seoul to JFK Airport in Queens. Koreatown lies at the northern edge of the humid subtropical climate zone, according to the Köppen climate classification , similar to Seoul , South Korea ; Koreatown has a moderately sunny climate, averaging between 2,400 and 2,800 hours of sunshine annually. Koreatown residents can enjoy an urban oasis at Flushing Meadows-Corona Park . Numerous branches of

6278-669: The short form Cháoyǔ has normally been used to refer to the standard language of North Korea and Yanbian , whereas Hánguóyǔ or the short form Hányǔ is used to refer to the standard language of South Korea. Korean is a member of the Koreanic family along with the Jeju language . Some linguists have included it in the Altaic family, but the core Altaic proposal itself has lost most of its prior support. The Khitan language has several vocabulary items similar to Korean that are not found in other Mongolian or Tungusic languages, suggesting

6364-486: The skin, a vital compound needed to make strong bone and muscle in the body. In many world religions, such as Hinduism , the Sun is considered to be a god , as it is the source of life and energy on Earth. The Sun was also considered to be a god in Ancient Egypt . Sunbathing is a popular leisure activity in which a person sits or lies in direct sunshine. People often sunbathe in comfortable places where there

6450-491: The solar light it receives. The actual illumination of the surface is about 14,000 lux, comparable to that on Earth "in the daytime with overcast clouds". Sunlight on Mars would be more or less like daylight on Earth during a slightly overcast day, and, as can be seen in the pictures taken by the rovers, there is enough diffuse sky radiation that shadows would not seem particularly dark. Thus, it would give perceptions and "feel" very much like Earth daylight. The spectrum on

6536-592: The solar magnetic cycle and many shorter periodic cycles. TSI provides the energy that drives Earth's climate, so continuation of the TSI time-series database is critical to understanding the role of solar variability in climate change. Since 2003, the SORCE Spectral Irradiance Monitor (SIM) has monitored Spectral solar irradiance (SSI) – the spectral distribution of the TSI. Data indicate that SSI at UV (ultraviolet) wavelength corresponds in

6622-408: The spectral composition changes primarily in respect to how directly sunlight is able to illuminate. When illumination is indirect, Rayleigh scattering in the upper atmosphere will lead blue wavelengths to dominate. Water vapour in the lower atmosphere produces further scattering and ozone, dust and water particles will also absorb particular wavelengths. The existence of nearly all life on Earth

6708-405: The store?' Response 예/네. ye/ne AFF Sunshine The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a requisite for vitamin D 3 synthesis and a mutagen . Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction every time it encounters

6794-605: The sunlight than was possible through glycolysis alone, and human population began to grow. During the Neolithic Revolution , the domestication of plants and animals further increased human access to solar energy. Fields devoted to crops were enriched by inedible plant matter, providing sugars and nutrients for future harvests. Animals that had previously provided humans with only meat and tools once they were killed were now used for labour throughout their lives, fueled by grasses inedible to humans. Fossil fuels are

6880-486: The surface is slightly redder than that on Earth, due to scattering by reddish dust in the Martian atmosphere. For comparison, sunlight on Saturn is slightly brighter than Earth sunlight at the average sunset or sunrise. Even on Pluto, the sunlight would still be bright enough to almost match the average living room. To see sunlight as dim as full moonlight on Earth, a distance of about 500 AU (~69  light-hours )

6966-441: The tense fricative and all the affricates as well. At the end of a syllable, /s/ changes to /t/ (example: beoseot ( 버섯 ) 'mushroom'). /h/ may become a bilabial [ɸ] before [o] or [u] , a palatal [ç] before [j] or [i] , a velar [x] before [ɯ] , a voiced [ɦ] between voiced sounds, and a [h] elsewhere. /p, t, t͡ɕ, k/ become voiced [b, d, d͡ʑ, ɡ] between voiced sounds. /m, n/ frequently denasalize at

7052-474: The timing of melatonin synthesis, maintenance of normal circadian rhythms , and reduced risk of seasonal affective disorder . Long-term sunlight exposure is known to be associated with the development of skin cancer , skin aging , immune suppression , and eye diseases such as cataracts and macular degeneration . Short-term overexposure is the cause of sunburn , snow blindness , and solar retinopathy . UV rays, and therefore sunlight and sunlamps, are

7138-430: The top of the atmosphere, sunlight is about 30% more intense, having about 8% ultraviolet (UV), with most of the extra UV consisting of biologically damaging short-wave ultraviolet. Direct sunlight has a luminous efficacy of about 93  lumens per watt of radiant flux . This is higher than the efficacy (of source) of artificial lighting other than LEDs , which means using sunlight for illumination heats up

7224-464: The underlying, partly historical morphology . Given this, it is sometimes hard to tell which actual phonemes are present in a certain word. The traditional prohibition of word-initial /ɾ/ became a morphological rule called "initial law" ( 두음법칙 ) in the pronunciation standards of South Korea, which pertains to Sino-Korean vocabulary. Such words retain their word-initial /ɾ/ in the pronunciation standards of North Korea. For example, ^NOTE ㅏ

7310-535: The web. Different bodies of the Solar System receive light of an intensity inversely proportional to the square of their distance from Sun. A table comparing the amount of solar radiation received by each planet in the Solar System at the top of its atmosphere: The actual brightness of sunlight that would be observed at the surface also depends on the presence and composition of an atmosphere . For example, Venus's thick atmosphere reflects more than 60% of

7396-487: Was first introduced to Korea in the 1st century BC, and remained the medium of formal writing and government until the late 19th century. Korean scholars adapted Chinese characters (known in Korean as Hanja ) to write their own language, creating scripts known as idu , hyangchal , gugyeol , and gakpil. These systems were cumbersome, due to the fundamental disparities between the Korean and Chinese languages, and accessible only to those educated in classical Chinese. Most of
