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.
Ingabe izinhlanzi ziyayibona imibala?
Iningi lazo libona imibala emibili lapho wena ubona emithathu. Ezinhlanzini ezingu-54 ezilapha, ezingu-19 zinokukala okuqondile kwe-spectrum kwamakhoni azo; amaforeli, usalmoni namakhaphu anezinhlobo ezine zamakhoni kubalwa nolubona i-ultraviolet, kanti oshaka banolulodwa futhi abayiboni imibala. Ngayinye kulezi ihlela ibhokisi elifanayo ngendlela ehlukile.
Umbala oyi-fluorescent
Lo mbala umunca amagagasi amafushane bese ewakhipha esemade, ngakho ukhanyiswa nangaphakathi. Yikho ngempela usinda emanzini anombala — kodwa i-quantum yield esetshenziswe lapha iyisilinganiso, akukhona ukukala kwalo pende.
Umbala okhanyayo — awulingiswanga
Ukukhanya kwe-phosphorescence kugcwaliswa ukukhanya bese kuncipha ebumnyameni, ngakho kuncike ekutheni isiyengo besisebusweni belanga isikhathi esingakanani nokuthi kudlule isikhathi esingakanani. Bekuyoba ukuqagela, ngakho asiqageli. Bhekana nalo mbala ngokwesimo sawo esijwayelekile kuphela.
Lokho le modeli ekushoyo nalokho engakushoyo
Yisilinganiso nje, akusona isithombe salokho inhlanzi ekubonayo.
