Indlela ezibona ngayo
Pavo cristatus ibona kanjani umhlaba?
Amashaneli amakhoni amane abonakalayo, izihlungi zamaconsi kawoyela nemininingwane elinganisiwe
I-Peafowl yaseNdiya iyi-tetrachromat ezwela i-violet. I-Microspectrophotometry ithole ama-pigment amane ekhoni eyodwa, kuyilapho amaconsi kawoyela kanye nemidiya ye-ocular kwakheka kabusha ukuzwela kwazo okusebenzayo; i-retinal anatomy inikeza umkhawulo ongemuva obaliwe wemijikelezo engu-20.6 ngedigri ngayinye, hhayi umkhawulo wokuziphatha.

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
Amakilasi amane anekhoni eyodwa kanye namaconsi kawoyela anombala akhiqiza iziqongo zokuzwela ezibikezelwe ku-432, 477, 537 kanye nama-nanometres angama-605. Lolu uhlelo oluzwela i-violet, hhayi oluzwela i-ultraviolet.
Ama-photoreceptor
I-tetrachromat ezwela i-Violet enamakhoni angawodwa amane, amaconsi akabili namaconsi kawoyela
Iziqongo zokuzwela kwama-cone
- Ikhoni eyodwa ezwela u-violet424 nm
- Ikhoni eyodwa yamagagasi amafushane458 nm
- Ikhoni eyodwa yegagasi elimaphakathi505 nm
- Ikhoni eyodwa yegagasi elide567 nm
Ukubona ekukhanyeni okuncane
U-Hart ulinganise ikilasi lenduku eyodwa kuma-retina aguqulelwe emnyama kusukela kwabesifazane abadala, kodwa akazange amise umkhawulo wokuziphatha wasebusuku. Ngakho-ke le phrofayela ayenzi isimangalo esilinganiselwe sombono wasebusuku.
Uma kuqhathaniswa nokubona komuntu
Abantu basebenzisa izigaba ezintathu zamakhoni; i-peafowl isebenzisa amakilasi amane okukhanya okubonakalayo namaconsi kawoyela anombala. Isibonisi se-RGB singagcizelela oku-violet okubonakalayo nokuhlukaniswa kombala, kodwa asikwazi ukudala ubukhulu obungeziwe bombala noma ukukhombisa lokho inyoni ekuzwayo ngokuzithoba.
Izici eziphawulekayo
- Iziqongo ze-pigment-pigment ezilinganisiwe ku-424, 458, 505 kanye nama-nanometer angu-567
- Amaconsi kawoyela kanye nokushintsha kwemidiya ye-ocular kubikezele ukuphakama okusebenzayo ku-432, 477, 537 kanye nama-nanometer angu-605
- Indawo ye-retina emaphakathi ifinyelela phezulu kumaseli e-ganglion angama-35,609 ngemilimitha yesikwele; Isilinganiso seNyquist sangemuva siyimijikelezo engu-20.6 ngedigri ngayinye
Imibuzo evame ukubuzwa
Pavo cristatus ibona kanjani umhlaba?

Yimiphi imibala Pavo cristatus engayibona?

Ukubona kuka-Pavo cristatus kucace kangakanani?
Isilinganiso se-retinal ganglion-cell sinikeza imijikelezo engu-20.6 ngedigri ngayinye endaweni esemaceleni. I-Hart ayizange ilinganise ukumbozwa kwenkambu yokubukwa kwekhanda lonke, ngakho leli khasi alinikezi ngamabomu inani ledigri.
Pavo cristatus ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-20.6 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-3 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
Pavo cristatus ibona kanjani ebumnyameni?
U-Hart ulinganise ikilasi lenduku eyodwa kuma-retina aguqulelwe emnyama kusukela kwabesifazane abadala, kodwa akazange amise umkhawulo wokuziphatha wasebusuku. Ngakho-ke le phrofayela ayenzi isimangalo esilinganiselwe sombono wasebusuku.
Yini eyisipesheli ngokubona kuka-Pavo cristatus?
Iziqongo ze-pigment-pigment ezilinganisiwe ku-424, 458, 505 kanye nama-nanometer angu-567. Amaconsi kawoyela kanye nokushintsha kwemidiya ye-ocular kubikezele ukuphakama okusebenzayo ku-432, 477, 537 kanye nama-nanometer angu-605. Indawo ye-retina emaphakathi ifinyelela phezulu kumaseli e-ganglion angama-35,609 ngemilimitha yesikwele; Isilinganiso seNyquist sangemuva siyimijikelezo engu-20.6 ngedigri ngayinye. I-telemetric eye-tracker yabonisa ukuthi i-peafowl ehamba ngokukhululekile ihlanganisa ukunyakaza kwamehlo nekhanda ngesikhathi sokushintsha kokubuka futhi ibe nokungabikho kwe-vestibulo-ocular reflex. Lolo cwaningo lwalinganisa izinsimbi zokubuka, hhayi umkhakha wokubuka wonke.
Ukubona kuka-Pavo cristatus kuqhathaniswa kanjani nokomuntu?
Abantu basebenzisa izigaba ezintathu zamakhoni; i-peafowl isebenzisa amakilasi amane okukhanya okubonakalayo namaconsi kawoyela anombala.
