I-eel yaseYurophu: le nhlanzi isibona kanjani isiyengo sakho

I-eel yaseYurophu: yimuphi umbala wesiyengo le nhlanzi ekwazi ngempela ukuwubona, ekujuleni kwakho nasemanzini akho. Izinhlobo zamakhoni ezingu-2, isiqongo ku-525 nm. Umehluko ohleliwe wemibala engu-54.

Kukaliwe kulolu hlobo

Iziqongo zamakhoni ziwukukala okuqondile kwalolu hlobo. Okunye konke kule modeli — i-optics yamanzi, umehluko, ibanga lokubona — kusengukulinganisela, futhi akukho kukho okubikezela ukuthi inhlanzi izohlasela yini. I-eel yakha kabusha izipigimenti zayo zokubona uma isishintshela ekufudukeleni olwandle, iqhubekele ngokushesha kosasibhakabhaka. Le phrofayela yisimo sayo esesishintshile; i-eel esemfuleni izwela oluhlaza ngokukalekayo.

Amarodi yiwo asebenzayo entathakusa, kuhwalala nasebusuku — okuyisikhathi abantu abaningi abadoba ngaso.

Thola le mibala

Emithathu ephume phambili, iseshwa ku-Amazon yakho. Ukuhleleka okungenhla kubalwa ngamanzi nangenhlanzi, ngaphambi kokuba lezi zixhumanisi zibe khona.

Imibuzo abantu abayibuzayo ngempela

I-eel yaseYurophu: ingabe le nhlanzi iyayibona imibala?

Yebo, kodwa kancane nje. Inezinhlobo zamakhoni ezingu-2, eziqonga ku-435 nm, 525 nm, ngakho inohlangothi olulodwa lombala lapho umuntu enezimbili.

Ivelaphi le datha?

I-microspectrophotometry eqondile, i-ERG noma ukuzwela kwe-spectrum okuhlolwe ngokuziphatha kwalolu hlobo.
