Isayensi
Zonke izimo, kubalwa nengosi yokubuka nosayizi wesiyengo
Ukujula
Ukuthi isiyengo sakho sihamba sijule kangakanani.
Amanzi
Khetha lawo asondelene kakhulu nawakho. Indlela elula yokuhlola ukujula kwe-Secchi: yehlisa idiski elimhlophe entanjeni bese uqaphela ukuthi linyamalala kuphi.
Inhlanzi ibheke
Ukuthi inhlanzi isibona ivelaphi isiyengo sakho. Lokhu kubalulekile kunalokho abadobi abaningi abakulindele.
I-chromophore
I-A2 ivamile ezinhlanzini zamanzi amtoti futhi idlulisela ukuzwela kungene kuwo obomvu. Izinhlobo eziningi ziyaguqukela phakathi kwalezi zimbili ngokwezinkathi zonyaka.
I-tapetum lucidum
Ungqimba olukhanyisayo ngemuva kwe-retina olucishe luphinde kabili ukubamba ukukhanya. Yikho le nhlanzi idla kahle kangaka lapho ukukhanya kuncane.
Irodi
Amarodi yiwo asebenzayo entathakusa, kuhwalala nasebusuku — okuyisikhathi abantu abaningi abadoba ngaso.
Le nhlanzi ayiyiboni imibala
Inohlobo olulodwa lwekhoni, ngakho ibona isiteshi esisodwa sokukhanya. Ukuhleleka kwemibala akunamsebenzi kuyo — okubalulekile ukuthi isiyengo sakho sikhanya noma simnyama kangakanani uma siqhathaniswa namanzi.
Lokho lawa manzi akudlulisayo
I-K_d ukuncipha okusabalele kokukhanya okwehlayo; i-c ukuncipha komsebe ngokomugqa wokubuka. Ukuxuba lokhu kokubili yiphutha elivamile kulo mkhakha.
