Hasken rana

haske Rana shine ɓangaren radiation na lantarki wanda Rana ke fitarwa (watau radiation na rana) kuma Duniya ta karɓa, musamman hasken da ake gani wanda ido na mutum ke iya fahimta da kuma infrared marar ganuwa (wanda mutane ke fahimta a matsayin dumi) da ultraviolet (wanda zai iya samun tasirin ilimin jiki kamar Hasken rana). Koyaya, a cewar American Meteorological Society, akwai "taron rikice-rikice game da ko duk ukun [...] ana kiransu haske, ko kuma ya kamata a yi amfani da wannan kalmar ne kawai ga ɓangaren bayyane na bakan". Bayan ya isa Duniya, Hasken rana yana warwatse kuma an tacewa shi ta cikin Yanayin duniya a matsayin Hasken rana lokacin da Rana ta kasance sama da sararin samaniya. Lokacin da girgije ba ya toshe hasken rana kai tsaye, ana samun sa a matsayin hasken rana, haɗuwa da haske mai haske da zafi mai haske (yanayin yanayi). Lokacin da girgije ya toshe ko kuma ya nunawa daga wasu abubuwa, hasken rana yana yadawa. Tushen ya kiyasta matsakaicin duniya tsakanin 164 watts zuwa 340 watts  a kowace murabba'in mita a cikin sa'o'i 24 a rana;  wannan adadi NASA ta kiyasta kusan kashi ɗaya cikin huɗu na matsakaicin hasken rana na Duniya.

Rashin hasken rana yana da sakamako mai kyau da mara kyau na kiwon lafiya, saboda yana da mahimmanci ga kira na bitamin D da kuma mutagen.

Hasken rana yana ɗaukar kimanin minti 8.3 don isa Duniya daga farfajiyar Rana. Wani photon da ke farawa a tsakiyar Rana kuma yana canzawa a duk lokacin da ya haɗu da wani caji zai ɗauki tsakanin shekaru 10,000 zuwa 170,000 don isa farfajiya. 

Hasken rana shine mahimmin abu a cikin photosynthesis, tsarin da shuke-shuke da sauran kwayoyin autotrophic ke amfani da shi don canza makamashi mai haske, yawanci daga Sun, zuwa makamashi na sinadarai wanda za'a iya amfani dashi don hada carbohydrates da kuma man fetur ga ayyukan kwayoyin.

Hasken rana shine hasken halitta na sararin ciki ta hanyar shigar da Hasken rana. Hasken rana shine yawan hasken rana da aka karɓa ta yanki ɗaya daga hasken rana.

Za'a iya hasken rana da na jikin baƙar fata  tare da zafin jiki na kimanin 5,800 K  (duba jadawalin). Rana tana fitar da radiation na EM a duk faɗin bakan lantarki. Kodayake radiation da aka ƙirƙira a cikin hasken rana ya kunshi mafi yawan rayukan x, shawo kan ciki da thermalization suna canza waɗannan photons masu ƙarfi zuwa photons masu ƙarancin makamashi kambin su kai saman Sun kuma ana fitar da su cikin sararin samaniya. A sakamakon haka, photosphere na Sun ba ya fitar da radiation X mai yawa (X-rays na rana), kodayake yana fitar da irin wannan "radiations mai wuya" kamar X-rays har ma da hasken gamma a lokacin hasken rana. Rana mai shiru (marar haske), gami da corona, yana fitar da nau'ikan nau'ikan raƙuman ruwa: X-rays, ultraviolet, haske mai ganuwa, infrared, da Raƙuman rediyo. Rashin zurfi daban-daban a cikin photosphere suna da yanayin zafi daban-daban, kuma wannan a wani bangare yana bayyana karkatarwa daga bakan baki.See video referenced in the sentence "For more details about the comparison of the black body with the AM0 spectrum, see this video"  at
