I-Arctic char: le nhlanzi isibona kanjani isiyengo sakho
I-Arctic char: yimuphi umbala wesiyengo le nhlanzi ekwazi ngempela ukuwubona, ekujuleni kwakho nasemanzini akho. Izinhlobo zamakhoni ezingu-4, isiqongo ku-600 nm. Umehluko ohleliwe wemibala engu-54.
Salvelinus alpinus
Kukaliwe esihlotsheni esiseduze I-UV ayikwazi ukuboniswa
Alukho ukukala kwe-spectrum okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe ku-ezinye izinhlobo zakwaSalvelinus, isihlobo salo esiseduze esinendlela yokudla efanayo. Bhekana nokuhleleka kwemibala njengokukhombisayo kunokuba yikho impela. Lolu hlobo lunekhoni ye-UV: cishe ingxenye engu-83% yokuzwela kwalelo khoni ingaphansi kuka-400 nm, lapho isikrini sefoni singenakukukhombisa lutho khona. Isiteshi se-UV sidwetshwe ngombala ongewona, njengoba sisho. I-retina yalo isebenzisa i-chromophore ye-A2 (i-porphyropsin), edlulisela ukuzwela kwamagagasi amade kudlulele kobomvu kunalokho i-retina ye-A1 ebiyokunika khona. Izinhlanzi eziningi zamanzi amtoti ziyaguqula isilinganiso se-A1/A2 ngenkathi yonyaka nangokushisa, ngakho ukuzwela kwangempela kuyantweza unyaka wonke.
Ukuzwela kwe-spectrum
| Iziqongo zamakhoni | λmax | I-chromophore |
|---|---|---|
| I-UV | 380 nm | A1 |
| Obufushane | 440 nm | A1 |
| Obuphakathi | 530 nm | A1 |
| Obude | 600 nm | A2 |
| Irodi | 515 nm | A1 |
Amarodi yiwo asebenzayo entathakusa, kuhwalala nasebusuku — okuyisikhathi abantu abaningi abadoba ngaso.
Ingxenye engu-83% yokuzwela kwekhoni ye-UV yalolu hlobo ingaphansi kuka-400 nm, ngaphandle kwakho konke isikrini esingakukhombisa.

I-UV ayikwazi ukuboniswa — Lolu hlobo lunekhoni ye-UV, kanti isikrini sefoni asikwazi ukukhipha i-ultraviolet. Isiteshi se-UV sidwetshwe ngombala ongewona, njengoba sisho. Qaphela futhi ukuthi i-UV imunceka ngokushesha ngaphansi kwamanzi futhi inyamalala kungakahambi namasentimitha emanzini anetanini.

Imibuzo abantu abayibuzayo ngempela
I-Arctic char: ingabe le nhlanzi iyayibona imibala?
Yebo. Inezinhlobo zamakhoni ezingu-4, eziqonga ku-380 nm, 440 nm, 530 nm, 600 nm. Lokho kuyinika izinhlangothi zombala ezingu-3, uma umuntu enezimbili.
Ivelaphi le datha?
Alukho ukukala okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe esihlotsheni sohlobo olufanayo olunendlela yokudla efanayo.
