Indlela ezibona ngayo
inyamazane ibona kanjani umhlaba?
Umbala o-orenji ubukeka umpunga; oluhlaza okwesibhakabhaka luyakhanya
Ekuseni nasentambama ehlathini, inyamazane ifunda umhlaba ngokuluhlaza okwesibhakabhaka okupholile nokuluhlaza okusawolintshi, iphila kakhulu ekukhanyeni kwe-wavelength emfushane kunathi. Njengoba ingenayo isihlungi selensi elisaphuzi elivikela amehlo abantu, imunca okuluhlaza kanye ne-ultraviolet eseduze lapho umbono wethu ufiphala. Umphumela kubazingeli: okubomvu okuvuthayo, okusicwazayo kangaka, kubukeka kumpunga ophuphile enyamazaneni.
Umuntu ≈ 60 cpd (20/20)
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.
Ukubona umbala
Okuluhlaza sasibhakabhaka nokuluhlaza-phuzi; i-orange ekhanyayo yokuzingela ibukeka imumethe futhi ingwevu kuyo. Izwela kakhulu emazingeni amafushane (oluhlaza sasibhakabhaka/UV eseduze).
Ama-photoreceptor
I-Dichromat (izinhlobo ezi-2 zamaseli e-cone), ayinaso isihlungi se-UV kwilensi
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka)455 nm
- M (oluhlaza-phuzi)537 nm
Ukubona ekukhanyeni okuncane
Isebenza ekuhweleleni; i-tapetum lucidum ne-retina egcwele amaseli e-rod ivelela ekuseni nasekushoneni kwelanga.
Uma kuqhathaniswa nokubona komuntu
Emini inyamazane ibona cishe ku-20/100 uma kuqhathaniswa ne-20/20 yakho futhi ibona imibala emibili kunemithathu. Lapho iqhubeka khona kusekupheleni komsuku: ifinyelela ku-ultraviolet eseduze ongeke uyibone, futhi amehlo ayo asentambama akudlula ekuseni nasentambama.
Izici eziphawulekayo
- Ibona ngamandla ukukhanya okufushane (oluhlaza sasibhakabhaka/UV eseduze)
- I-orange ekhanyayo yokuzingela ibonakala ingwevu
- Imininingwane emincane emincane, ukuzwela okukhulu ekunyakazeni
Imibuzo evame ukubuzwa
inyamazane ibona kanjani umhlaba?
Ekuseni nasentambama ehlathini, inyamazane ifunda umhlaba ngokuluhlaza okwesibhakabhaka okupholile nokuluhlaza okusawolintshi, iphila kakhulu ekukhanyeni kwe-wavelength emfushane kunathi. Njengoba ingenayo isihlungi selensi elisaphuzi elivikela amehlo abantu, imunca okuluhlaza kanye ne-ultraviolet eseduze lapho umbono wethu ufiphala. Umphumela kubazingeli: okubomvu okuvuthayo, okusicwazayo kangaka, kubukeka kumpunga ophuphile enyamazaneni. Okuluhlaza sasibhakabhaka nokuluhlaza-phuzi; i-orange ekhanyayo yokuzingela ibukeka imumethe futhi ingwevu kuyo. Izwela kakhulu emazingeni amafushane (oluhlaza sasibhakabhaka/UV eseduze).
Yimiphi imibala inyamazane engayibona?
Okuluhlaza sasibhakabhaka nokuluhlaza-phuzi; i-orange ekhanyayo yokuzingela ibukeka imumethe futhi ingwevu kuyo. Izwela kakhulu emazingeni amafushane (oluhlaza sasibhakabhaka/UV eseduze). I-Dichromat (izinhlobo ezi-2 zamaseli e-cone), ayinaso isihlungi se-UV kwilensi
Ukubona kuka-inyamazane kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-6 ngedigri (20/100), kanti umuntu ufinyelela cishe ku-60 cpd (20/20). Ibanga layo lokubona lisabalala cishe ngo-310°.
inyamazane 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.
inyamazane ibona kanjani ebumnyameni?
Isebenza ekuhweleleni; i-tapetum lucidum ne-retina egcwele amaseli e-rod ivelela ekuseni nasekushoneni kwelanga.
Yini eyisipesheli ngokubona kuka-inyamazane?
Ibona ngamandla ukukhanya okufushane (oluhlaza sasibhakabhaka/UV eseduze). I-orange ekhanyayo yokuzingela ibonakala ingwevu. Imininingwane emincane emincane, ukuzwela okukhulu ekunyakazeni. Amehlo enyamazane alungiselelwe ama-wavelength amafushane kangangokuthi ijakethe eligeziwe kabusha, elelashwe ngokukhanyisa kwe-ultraviolet okusezinhlanzekisweni eziningi, lingakhanya njengesibani kuyo, ngisho nayilapho iphethini yayo yokucasha yenza umsebenzi emehlweni ethu.
Ukubona kuka-inyamazane kuqhathaniswa kanjani nokomuntu?
Emini inyamazane ibona cishe ku-20/100 uma kuqhathaniswa ne-20/20 yakho futhi ibona imibala emibili kunemithathu. Lapho iqhubeka khona kusekupheleni komsuku: ifinyelela ku-ultraviolet eseduze ongeke uyibone, futhi amehlo ayo asentambama akudlula ekuseni nasentambama.
