Indlela ezibona ngayo
isikhova ibona kanjani umhlaba?
Sishintshanisa umbala ngokubona ngokukhanya kwezinkanyezi
Isikhova sishintshanisa umbala nokukhanya. Amehlo aso amakhulu agcwele ama-receptor okukhanya okuluvivi, okwenza sibe ngesinye sabazingeli bobusuku abahle kunabo bonke abaphilayo, yize enza ubumnyama bube cishe bumnyama-mhlophe. Lawo mehlo ayizimbobo ezinganyakaziswa ezingakwazi ukuphenya ezindaweni zawo, okuyiyona kanye into eyenza isikhova siphenye ikhanda laso lonke, futhi kude ngokumangalisayo.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-isikhova kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-7 ngedigri (20/86 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-110°.
isikhova ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-7 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-9 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 isikhova engayibona?
Umbala omncane kakhulu; ikwenzelwe ngokuphelele ukuthola ukukhanya nokunyakaza ebusuku.
Ama-photoreceptor
Ibuswa amaseli e-rod futhi impofu emaselini e-cone (cishe i-monochromat ebusuku)
Iziqongo zokuzwela kwama-cone
- I-rod (i-rhodopsin)503 nm
isikhova ibona kanjani ebumnyameni?
Enye yezinhle kunazo zonke zezilwane: ingazingela ekukhanyeni kwezinkanyezi.
Ukubona kuka-isikhova kuqhathaniswa kanjani nokomuntu?
Isikhova sibona umbala omncane kakhulu kunawe, futhi kubanga elifushane. Kokuyithi ubumnyama sishiya umbono wakho kude emuva, sibona inyamazane ngokukhanya kwezinkanyezi lapho wena ubungaba yimpumputhe ngokusebenzayo.
Yini eyisipesheli ngokubona kuka-isikhova?
- Amehlo ashaywe njengezimbobo angeke azungeze (izungezisa ikhanda kufika ku-270°)
- Aqondiswe ngaphambili ukuze abale amabanga
- Ukuzwela okuhle kakhulu ekukhanyeni okuncane
Imithombo yesayensi
- Martin (1986)
- Harmening & Wagner (2011)
