Indlela ezibona ngayo
ifereti ibona kanjani umhlaba?
Umzingeli womgodi, wokukhanya okuncane, wemininingwane emincane
Ifereti liphuma kubazingeli bemigodi, futhi amehlo alo asabonisa lelo fa. Umbono uluvivi ezinhlangothini futhi umbala uphansi, kunalokho ulungiselelwe ubumnyama obuseduze bomgodi noma ukukhanya okuyingxenye kokusa nokuhlwa. Lihlulela umhlaba ezingeni lomhlaba, lapho iphunga nokunyakaza kubaluleke khona kunesithombe esicijile nesinombala.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-ifereti kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-4 ngedigri (20/150), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-270°.
ifereti ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-4 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-15 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
Ukuqhathanisa imibala
How each colour shifts when seen through this animal's eyes, using the same colour model as the app. Tones a screen can't emit (such as ultraviolet) are shown as an approximation.
Yimiphi imibala ifereti engayibona?
Ukubona umbala oluhlaza sasibhakabhaka-phuzi okulinganiselwe; kwenzelwe ukuqhathanisa nokunyakaza ekukhanyeni okuncane.
Ama-photoreceptor
I-Dichromat (izinhlobo ezi-2 zamaseli e-cone), ibuswa amaseli e-rod
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka)430 nm
- L (oluhlaza)558 nm
ifereti ibona kanjani ebumnyameni?
Ukubona okuhle kakhulu ekukhanyeni okuncane ukuze izingele emithumeni nasekukhanyeni okumaphakathi.
Ukubona kuka-ifereti kuqhathaniswa kanjani nokomuntu?
Ku-20/150 ifereti libona imininingwane emincane kakhulu kune-20/20 yakho, futhi imibala emibili kuphela efiphele. Uma ilanga selishonile, umbono walo wokukhanya okuncane, olungiselelwe ukuhlwa nomgodi, ushiya owakho emuva.
Yini eyisipesheli ngokubona kuka-ifereti?
- Uchwepheshe wasekuhweleleni
- Ubukhali obuphansi
- Inkambu yokubona esemhlabathini
Imithombo yesayensi
- Calderone & Jacobs (2003)
