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.

Ukucaca kokubona20.6 cpd · No clinical equivalent; 20.6 cpd retinal Nyquist estimate

Umuntu ≈ 60 cpd (20/10)

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.

Yimiphi imibala Pavo cristatus engayibona?

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.

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.

Ukubona kuka-Pavo cristatus kuqhathaniswa kanjani nokomuntu?

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.

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
