Hona joale, batho ba bangata ba lumela hore likhalase tse theko e boima haholo li molemo!Ho utloisisa psychology ena ea bareki, mabenkele a optical hangata a sebelisa refractive index e le ntlha ea ho rekisa ho eketsa theko ea likhalase e le ho fumana melemo e phahameng ea moruo.Ha index ea refractive e phahame, lense ea lense e le mosesaane, kereiti e phahame, 'me theko e phahame!Joale na ke 'nete hore ho phahamisa index ea refractive ea likhalase, ho molemo?Ha re bue ka eona.
Lilense tse ntle tsa optical li lokela ho bua ka lilense tse nang le lisebelisoa tse ntle tsa optical, tse bonahatsoang ke phetisetso ea khanya e phahameng, ho hasana ha nyane, ho hanyetsa ho apara hantle, tšireletso e matla ea ultraviolet, le ts'ireletso e ntle ea mahlaseli.
