I-Parallax: konke odinga ukukwazi

izinhlobo ze-parallax

La upharafini ukuchezuka kwe-angular yendawo ebonakalayo yento, kuye ngendawo yokubuka ekhethiwe. Lokhu kunezinhlelo zokusebenza ezithile emhlabeni wesayensi yezinkanyezi kokubili ukukala amabanga kanye nokubona ngeso lengqondo izinto zasemkhathini. Abantu abaningi abazi ukuthi yini i-parallax.

Ngakho-ke, kulesi sihloko sizokutshela ukuthi i-parallax iyini, yiziphi izici zayo nokubaluleka kwayo.

yini i-parallax

upharafini

I-Parallax ihlanganisa ukubeka iminwe yakho phambi kwamehlo akho. Ingemuva akufanele lifane. Ukubheka kuqala ngeso elilodwa bese kuthi kwelinye ngaphandle kokunyakazisa ikhanda noma umunwe, kuyabonakala ukuthi ukuma komunwe kuyashintsha ngokuphathelene nengemuva. Uma sisondeza umunwe wethu esweni futhi sibheke futhi ngelinye iso bese sibheka ngelinye, izindawo zeminwe emibili ngemuva zimboza ingxenye enkulu.

Lokhu kungenxa yokuthi kunamasentimitha ambalwa phakathi kwamehlo, ngakho umugqa ongokomfanekiso ohlanganisa iminwe neso elilodwa wenza i-engeli enomugqa ocatshangelwayo oxhuma iminwe kwelinye iso. Uma sinweba le migqa emibili ecatshangwayo iye phansi, sizoba namaphuzu amabili ahambisana nezindawo ezimbili ezihlukene zeminwe.

Lapho sisondeza umunwe esweni, i-engeli inkulu futhi kukhulu ukugudluka okubonakalayo. Uma amehlo ebeqhelelene kakhulu, i-engeli eyakhiwe imigqa emibili ibizokhula kakhulu, ngakho ukugudluka okusobala komunwe ngemuva bekuzoba kukhulu.

i-parallax ku-astronomy

ukubonwa kwesibhakabhaka

Lokhu kuyasebenza nakumaplanethi. Empeleni, inyanga ikude kangangokuthi asikwazi ukubona umehluko uma siyibuka ngamehlo ethu. Kodwa uma sibheka iNyanga esibhakabhakeni esigcwele izinkanyezi ezindaweni ezimbili eziqhelelene ngamakhilomitha angamakhulu, siphawula izinto ezimbalwa. Kusukela endaweni yokuqala yokubuka izinto sasibona unqenqema lwenyanga ebangeni elithile ukusuka enkanyezini ethile, kanti endaweni yesibili unqenqema olufanayo luzoba sebangeni elihlukile kunenkanyezi efanayo.

Ukwazi ukufuduka okusobala kweNyanga ngokuphathelene nesizinda esinezinkanyezi kanye nebanga phakathi kwezindawo ezimbili zokubuka izinto, leli banga lingabalwa ngosizo lwe-trigonometry.

Lokhu kuhlola kusebenza kahle kakhulu ngoba ukususwa okusobala kweNyanga ngokuphathelene nesizinda sesibhakabhaka esigcwele izinkanyezi kukhulu kakhulu lapho kushintsha indawo yomuntu obukele. Izazi zezinkanyezi ziye zashintsha le ndlela evamile ukuze ivumelane nesimo lapho umuntu obukele ebona inyanga emkhathizwe kuyilapho omunye engaphezulu kwayo. Isisekelo sikanxantathu silingana ne-radius yomhlaba, futhi i-engeli eyenzayo ne-vertex yenyanga "i-parallax enezingqimba enkabazwe." Inani layo liyimizuzu engama-57,04 ye-arc noma ama-radians angu-0,95.

Eqinisweni, ukufuduka okukhulu, njengoba lilingana nobubanzi obuphindwe kabili benyanga egcwele. Lesi ubukhulu obungalinganiswa ngokunemba okwanele ukuze uthole inani elihle lebanga eliya eNyangeni. Leli banga, elibalwe ngosizo lwe-parallax, livumelana kahle kakhulu nezibalo ezitholwe indlela yakudala yethunzi ephonswe nguMhlaba ngesikhathi sokufiphala kwenyanga.

Ngeshwa izimo ngo-1600 azizange zivumele ukubeka indawo yokuhlola kude ngokwanele, okwathi, kuhlangene namabanga amade okwatholakala kuwo amaplanethi, kwenza ukufuduka okwakubonakala kungemuva kwesibhakabhaka esigcwele izinkanyezi kwaba kuncane kakhulu ukuba kube okunembile.

Izinhlobo

izinkanyezi namaplanethi

Singasho ukuthi kunezinhlobo ezimbili ze-parallax:

  • I-Geocentric Parallax: Lapho irediyasi esetshenziswayo iwumhlabathi.
  • I-Spiral Centroid noma i-Parallax Yonyaka: Lapho irediyasi esetshenziswayo iwukuzungeza komhlaba ilanga.

Uma sibona inkanyezi ngoMasingana noJuni, uMhlaba uyobe usezindaweni ezimbili ezihlobene emzileni womhlaba. Singakwazi ukukala izinguquko endaweni ebonakalayo yenkanyezi. Uma i-parallax inkulu, inkanyezi isondelana. Kulokhu, i-parsec isetshenziswa njengeyunithi, echazwa njenge-reciprocal ye-parallax engunxantathu elinganiswa ngamasekhondi e-arc.

uphenyo lwe-parallax

Kamuva kwafika izibonakude ezaqanjwa noma zashintshwa usosayensi wase-Italy uGalileo Galilei. Izibonakude zingakala kalula amabanga angama-angular angenakubonwa ngeso lenyama.

Amaplanethi ane-parallax enkulu kunawo wonke amaplanethi aseduze, okuyiMars kanye neVenus. I-Venus iseduze kakhulu nelanga phakathi nokudlula kwayo okuseduze kangangokuthi ayikwazi ukubonwa ngaphandle kwalapho ibonakala ngemuva kwediski yelanga phakathi nokuhamba kwayo. Bese, okuwukuphela kwesimo lapho i-parallax ikalwa khona yi-Mars.

Isilinganiso sokuqala se-telescopic se-planetary parallax senziwa ngo-1671. Laba babukeli ababili kwakuyisazi sezinkanyezi esingumFulentshi uJean Richel, owahola uhambo lwesayensi oluya eCayenne, eFrench Guiana, nesazi sezinkanyezi sase-Italy nesiFulentshi uGiovanni Cassini, owasala eParis. Babuka i-Mars ngesikhathi esifanayo ngangokunokwenzeka futhi baphawula indawo yayo uma kuqhathaniswa nenkanyezi eseduze. Ngokubala umehluko wesikhundla esibhekiwe, ukwazi ibanga ukusuka eCayenne ukuya eParis, ibanga elisuka ku-Mars ngesikhathi sokulinganisa liyabalwa.

Uma isiqediwe, isikali semodeli ye-Kepler sizotholakala, okusivumela ukuba sibale wonke amanye amabanga esistimu sonozungezilanga. UCassini ulinganisele ibanga le-Sun-Earth kumakhilomitha ayizigidi eziyi-140, Ngamakhilomitha ayizigidi ezingu-9 kunesibalo sangempela, kodwa imiphumela yomzamo wokuqala ibe mihle kakhulu.

Kamuva, kwenziwa izilinganiso ezinembe kakhudlwana zeplanethi ye-parallax. Ezinye kuVenus, lapho zidlula khona ncamashi phakathi koMhlaba neLanga, zingabonakala njengendilinga encane emnyama kudiski yelanga. Lezi zindlela zokuthutha zenzeka ngo-1761 no-1769. Uma kusuka ezindaweni ezimbili ezihlukene zokuhlola kungaqinisekiswa ukuthi umzuzu wokuxhumana kweVenus nediski yelanga kanye nomzuzu wokuhlukana kwayo nediski yelanga, okungukuthi, ubude besikhathi sokuhamba buhlukile ukusuka endaweni eyodwa kuya kwesinye. Ngokwazi lezi zinguquko kanye nebanga phakathi kwama-observatory amabili, i-parallax yeVenus ingabalwa. Ngale datha ungakwazi ukubala ibanga eliya eVenus bese uya eLangeni.

Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi iyini i-parallax nezici zayo.
