Yimiphi imibala ebonwa yizinja?

Kwaphela isikhathi eside kunenkolelo yokuthi izinja zibona umhlaba ngokumnyama nokumhlophe. Kodwa kusukela ngo-2012, ngenxa yemizamo yomcwaningi u-Jay Neitz, ochwepheshe be-Russian Academy of Sciences nabanye abacwaningi, sinesizathu sokujabula ngabangane bethu abanemilenze emine! Izwe kubo akusona isithombe esiyisicefe esimnyama nesimhlophe. Izinja zibuye zihlukanise imibala, nakuba kungeyona yonke i-spectrum.

Iso lomuntu linezigaxa ezintathu zesikhala sombala. Singakwazi ukuhlukanisa imibala ephuzi, eluhlaza, eluhlaza okwesibhakabhaka nokubomvu. Kodwa izinja zinezigaxa ezimbili kuphela. Bangakwazi ukukhomba kuphela okuphuzi nokuluhlaza okwesibhakabhaka, kodwa abakwazi ukuhlukanisa phakathi kokuphuzi-okuluhlaza kanye nokubomvu-owolintshi. Hhayi lokho kukhetha okuningi, kodwa kusengcono kunesithombe esimnyama nesimhlophe.

Ochwepheshe be-Russian Academy of Sciences benze ucwaningo olwasiza ukuqonda kangcono amandla okubuka enja. Umsebenzi wabo kwakuwukuthola ukuthi izinja ziyalithatha yini izinga lokukhanya. Ukuhlolwa kwakuhilela izinja eziyi-8 zezinhlobo neminyaka ehlukene. Kwabekwa amabhokisi ama-4 phambi kwabo, elinye lawo linesitsha esinokudla okumnandi. Iphepha elinemibala lalibekwe ngaphezu kwebhokisi ngalinye. Zazine zazo, kanye namabhokisi: okuphuzi okukhanyayo, okuphuzi okumnyama, okuluhlaza okwesibhakabhaka nokuluhlaza okwesibhakabhaka okumnyama. Iqabunga eliphuzi elimnyama lalihlale lilenga phezu kwebhokisi lokudla okumnandi. Esigabeni sokuqala sokuhlolwa, izinja zazivunyelwe ukuhlola amabhokisi nalokho akuqukethe futhi zikufanise neshidi elinemibala. Ngezindlela ezintathu, izinja zaqonda ukuthi iqabunga eliphuzi elimnyama lalikhomba ibhokisi lokudla. Ososayensi base benciphisa inani lamabhokisi laba amabili. Izinja kwakufanele zikhethe phakathi kophawu oluphuzi ngokukhanyayo noluluhlaza okwesibhakabhaka. Uma izinja ziqondiswa ukukhanya, zingakhetha umbala ohlaza okwesibhakabhaka, ngoba. kufana nokukhanya okuphuzi okumnyama. Kodwa inja ngayinye yokuhlola yakhetha iqabunga eliphuzi elikhanyayo.

Imiphumela yokuhlolwa ayisho ukuthi izinja azikuhlukanisi nhlobo ukukhanya kwemibala. Kodwa babonisa ukuthi emini, inja igxila embala, hhayi ezingeni lokukhanya.

Izinja zinombono "we-bicolor". Abacwaningi baphawula ukuthi izinja zibona umhlaba ngendlela efanayo njengoba abantu abangaboni imibala bewubona.

Iqiniso elithakazelisayo. Izinja eziqondisayo, ezibheka ukukhanya kwethrafikhi, aziqondiswa umbala okhanyayo, kodwa ngendawo yesignali.

Uma uza esitolo sezilwane ukuze uthole ithoyizi lenja, amehlo akho agijima kakhulu. Ziningi kakhulu zazo: izinhlobo nemibala eminingi. Amanye amamodeli angama-shades athulisiwe, amanye anamanzi, akhanyayo, avela esigabeni esithi "khipha amehlo akho". Ucabangani, ingabe umbala wethoyizi ubalulekile enja ngokwayo?

Njengoba izinja zingakwazi ukuhlukanisa phakathi kwemibala ephuzi neluhlaza okwesibhakabhaka, kunconywa ukukhetha amathoyizi alawa ma-shades wemidlalo nokuqeqeshwa. Inja izobona ngokucacile izinto eziluhlaza okwesibhakabhaka nokuphuzi otshanini noma eqhweni. Kodwa ibhola elibomvu emehlweni enja lizohlangana notshani obuluhlaza: isilwane esifuywayo sizobona kokubili ngokumpunga.

Ingabe lokhu kusho ukuthi kungcono ungathengi ibhola elibomvu? Futhi ngayo eluhlaza, epinki newolintshi? Cha. Uma inja ithembele ekuboneni kuphela, khona-ke bekungaba nzima ngempela ngayo ukuthola amathoyizi ale mibala. Kodwa ngaphezu kombono, izilwane ezifuywayo zinomuzwa obukhali wokuhogela - ngenxa yalokho, inja ingathola kalula ithoyizi lanoma yimuphi umbala kunoma iyiphi indawo. Ngakho-ke akufanele ulengiswe umbala wethoyizi.

Akukhona nje kuphela ukubona, kodwa futhi iphunga lisiza inja ukuthola ithoyizi. Ngenxa yomqondo obukhali wokuhogela, inja ithola kalula ithoyizi lanoma yimuphi umbala.

Uma ikhono lokuhlukanisa phakathi kwemibala ephuzi neluhlaza okwesibhakabhaka lingazange likududuze futhi usadabukile ngesilwane sakho esifuywayo, khumbula ukuthi izinja zibona kahle ebumnyameni futhi zihumusha ngokuphelele izithunzi ezimpunga. Futhi umkhakha wabo wokubuka ubanzi kakhulu kunowethu. Izinja ziyakwazi ukubona kahle izinto ezihambayo ebangeni elingamamitha angu-400 ngisho nasezikhanyisweni ezimbi kakhulu, esingakaze siziphuphe. Futhi yonke into engakwazi ukuphinda yenziwe ngombono, umuzwa obukhali kakhulu wokuhogela uzophela.

Ikhono lokuhlukanisa imibala yezilwane alibalulekile kakhulu kunekhono lokubona ebusuku, ukubamba ukunyakaza kude, ukuzwa nokuhogela ngokucijile.

Ngakho singabajabulela kuphela!
