Indlela ezibona ngayo
igundane ibona kanjani umhlaba?
Ibona i-ultraviolet cishe ebumnyameni
Imininingwane ecolekile icishe inyamalale kugundane, elingehluleka cishe noma yiliphi ishadi lamehlo. Umhlaba walo uluvivi futhi ucishe ube nombala owodwa, ukhanyiselwe ubusuku, kodwa lithatha okuthile esingeke sikubone: ukukhanya kwe-ultraviolet. Endle lokho kungaguqula amamaki ephunga lezilwane eziyingozi nezimbangi zibe yizimpawu ezikhanyayo ezisakazeke phansi.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-igundane kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-0.5 ngedigri (20/1200), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-280°.
igundane ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-0.5 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-120 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 igundane engayibona?
I-dichromacy eluhlaza + ultraviolet. Imininingwane yendawo embi kakhulu, kodwa izwela amaphethini e-UV angabonakali kithi.
Ama-photoreceptor
I-Dichromat eneseli e-cone elizwela i-UV, ibuswa kakhulu amaseli e-rod
Iziqongo zokuzwela kwama-cone
- UV (S)360 nm
- M (oluhlaza)508 nm
igundane ibona kanjani ebumnyameni?
Isebenza ebusuku, i-retina ibuswa amaseli e-rod; ihle kakhulu cishe ebumnyameni.
Ukubona kuka-igundane kuqhathaniswa kanjani nokomuntu?
Ubuqondi begundane, cishe ku-20/1200, buyingxenyana encane ye-20/20 yakho. I-retina yalo yinye enye indaba: yakhelwe ubumnyama obuseduze lapho okwakho kuwohloka khona, inekhoni le-wavelength emfushane elifinyelela ku-ultraviolet, ibhande elivalelwe kuwe ngokuphelele.
Yini eyisipesheli ngokubona kuka-igundane?
- Ibona i-ultraviolet
- Ubukhali obuphansi kakhulu
- Yakhelwe ubusuku
