Indlela ezibona ngayo

i-reindeer ibona kanjani umhlaba?

Ibona i-UV; amehlo asebusika aphenduka aluhlaza okwesibhakabhaka

I-reindeer ibona i-Arctic nge-ultraviolet, futhi ensimini yamaqhwa amhlophe angenamkhawulo lokho kushintsha yonke into. Iqhwa libuyisa i-UV ngokukhanya, kuyilapho i-lichen, uboya nomchamo kumunca. Kwi-reindeer lokhu kufundeka njengezimpawu ezimnyama ezisakazeke emhlabeni okhanyayo, kwembula ukudla nengozi okungase kunyamalale ekucwazimuleni emehlweni ethu.

Umuntu ≈ 60 cpd (20/10)

Ukubona kuka-i-reindeer kucace kangakanani?

Amehlo ayo ahlukanisa cishe ama-cycles angu-6 ngedigri (20/100 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-340°.

i-reindeer ubona kanjani umuntu?

Amehlo ayo ahlukanisa cishe imijikelezo engu-6 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-10 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.

Yimiphi imibala i-reindeer engayibona?

I-dichromacy eluhlaza sasibhakabhaka-phuzi eyeluliwe kuya ku-ultraviolet: izinto ezimunca i-UV (izilwane ezizingelayo, umchamo, i-lichen) zibonakala njengezimpawu ezimnyama eqhweni.

I-Dichromat enokuzwela i-UV; i-tapetum lucidum eshintsha umbala ngokwesizini

Iziqongo zokuzwela kwama-cone

S (oluhlaza sasibhakabhaka/othambekele ku-UV)450 nm
L (oluhlaza)550 nm

i-reindeer ibona kanjani ebumnyameni?

Ebusika i-tapetum lucidum iba luhlaza sasibhakabhaka, isabalalisa ukukhanya okwengeziwe futhi iphindaphinda ukuzwela cishe izikhathi ezi-1000 ngobusuku bomkhathi wasenyakatho.

Ukubona kuka-i-reindeer kuqhathaniswa kanjani nokomuntu?

Iqaphela i-ultraviolet ongeke ukubone, okuguqula ubumhlophe obukhanyayo beqhwa bube yimephu efundekayo, enesakhiwo. Emininingwaneni evamile i-reindeer isebenza cishe ku-20/100 kune-20/20 yakho, futhi ibona imibala emibili kunemithathu.
