jyaamitiya albedo

khagol vigyaan mein, ack khagoliya pind kaa jyaamitiya albedo isaki vaastavik chamak kaa anupaat haye jaisa kii prakaash srot seey dekhaa jaataa haye (i.ee. shoonya charan konn parr) ack "aadarsh" sapaat, poori tarah seey pratibimbit, usee cross-section key saath visarjit scattering (lambertian) disk key liye. (yeh charan konn prakaash path kii disha koo sandarbhit kartaa haye aur prakashiki yaa electronics mein isake samanya arth mein ack charan konn naheen haye.)
visarjit prakirnan kaa tatparya haye kii vikiran samtaapaatmak roop seey paraavartit hotaa haye jisamen ghatana prakaash srot key sthaan kii koee smriti naheen hoti haye. shoonya charan konn roshni kii disha mein dekhane key anuroop haye. prithvi-baddh paryavekshakon key liye, yeh taba hotaa haye jaba prashn mein shareer virodh mein aur grahan parr hotaa haye.
drishya jyaamitiya albedo jyaamitiya albedo matra koo sandarbhit kartaa haye jaba drishya spectrum mein kewal vidyut chumbakiya vikiran key liye lekha hotaa haye.
havaa rahit shareer.
vayuheen pindon kii satah samagri (regolith) (vaastav mein, saur mandal mein adhikansh nikaay) dridhata seey gair-lambertian hain aur virodh prabhaav pradarshit karate hain, joe prakaash koo seedhe apane srot parr pratibimbit karane kii ack majboot pravritti haye, naa kii prakaash koo failaane key liye.
inn nikaayon key jyaamitiya albedo koo nirdhaarit karna mushkil hoe sakata haye kyonki unakaa paraavartan shoonya key paas charan konon kii ack chhoti seema key liye dridhata seey charam parr haye. iss shikhar kii taakat shareer key beach spasht roop seey bhinn hoti haye, aur kewal paryaapt chhote charan konon parr maap karke paaee jaa sakati haye. iss tarah key maap aamtaur parr ghatana prakaash key bahut karib paryavekshak key aavashyak sateek sthaan key kaaran kathin hotey hain. udaaharan key liye, chandrama koo prithvi seey bilkul shoonya charan konn parr kabhi naheen dekhaa jaataa haye, kyonki taba yeh grahan hoe rhaa hotaa haye. anya saur mandal nikaay samanya roop seey bilkul shoonya charan konn parr bhee vipaksh mein naheen dekhe jaate hain, jaba taka kii way bhee apani kaksha key aarohi yaa avrohi node parr ack saath sthit naa houn, aur isaliye grahan parr sthit houn. vyavhaar mein, chhote gair-shoonya charan konon parr maap kaa upayog una maapdandon koo praapt karane key liye kiya jaataa haye joe shareer key liye dishaatmak paraavartan gunon (hapke mapdand) koo darshaate hain. inke dwara varnit paraavartan falan koo jyaamitiya albedo kaa anuman praapt karane key liye shoonya charan konn mein bahishkrit kiya jaa sakata haye.
bahut ujjwal, thhos, vayuheen vastuon jaise kii shani key chandrama encaladus aur tethys key liye, jinaki kull paraavartan (bonned albido) ack key karib haye, ack majboot virodh prabhaav uchch bandhan albido key saath milkar unhein ekataa key oopar ack jyaamitiya albido detaa haye (encaladus key mamle mein 1.4). prakaash adhimaantah apane srot parr seedhe vaapas paraavartit hotaa haye, yahaan taka kii ghatana key cumm konn parr bhee jaise kii anga parr yaa dhalaan seey, jabaki ack lambertian satah vikiran koo bahut adhik vyaapak roop seey bikher degi. ekataa key oopar ack jyaamitiya albido kaa arth haye kii srot kii or prati ikai thhos konn mein bikhare prakaash kii teevrata kissy bhee lambertian satah key liye sambhav seey adhik haye.
sitaare.
taare aantarik roop seey chamakate hain, lekin way prakaash koo bhee pratibimbit curr sakate hain. ack nikat dwiaadhaari taaraa pranali mein dhruvmapi kaa upayog ack taare seey dusare seey paraavartit prakaash koo maapane key liye kiya jaa sakata haye (aur isake vipareet) aur isaliye dou sitaaron key jyaamitiya albido koo bhee. yeh kaary spica pranali key dou ghatakon key liye puuraa kiya gayaa haye, jisamen spica aeye aur bee key jyaamitiya albido koo kramshah 0.0361 aur 0.0136 key roop mein maapa jaa rhaa haye. taaron key jyaamitiya albedo samanya roop seey chhote hotey hain, soorya key liye 0.001 kaa maan apekshit haye, lekin germ yaa cumm gurutvaakarshan key liye (i.ee. vishal) paraavartit prakaash kii matra spica pranali mein taaron kii tulanaa mein kaee gunaa honey kii ummeed haye.
samatulya paribhaashaaen.
samtal satah key kaalpanik mamle key liye, jyaamitiya albido satah kaa albido haye jaba prakaash vikiran kii kiran dwara pradaan kiya jaataa haye joe satah key lambavat aatee haye.
udaaharan.
prashnagat shareer kii satah aur vayumandaliya gunon key aadhar parr jyaamitiya albido bandhan albido seey badaa yaa chhota hoe sakata haye. kuchh udaaharan -
