Umsebenzisi wenethiwekhi yokuxhumana nomphakathi eshicilele isifinyezo lapho athumba khona ekhishini lakhe ekukhanyiseni kwe-ultraviolet. Ngakolunye uhlangothi, isithombe sibukeka singajwayelekile, kwesinye - sikwenza kwenze ukucabanga.
Iqiniso ngukuthi ngokukhanya okujwayelekile, ikhishi libukeka lihlanzekile ngokuphelele, kepha isibani se-UV sikhombise isimo sangempela sezinto.
Umbhali waphawula ukuthi uyayijabulela ekhishini cishe iminyaka eyi-8. Ngemuva kokutadisha kwakhe, isibani se-ultraviolet wazama ukugeza ukungcola, kepha akazange aphume. Yize bengamcasuli ngokukhethekile. Uthanda nje ukwazi ukuthi amabala anjalo ajwayelekile.
Ubuye watshela ukuthi Wenze kanjani lesi sithombe. Wabeka ikhamera etafuleni abeke umzuzwana wemizuzwana eyi-15, ngemuva kwalokho waqala ukushayela ithoshi ngesibani se-UV ekhishini.
Umbhali waphawula ukuthi i-wavengethth kufanele ibe ngu-365 nm, ngaphandle kwalokho isithombe esihlukile ngeke sisebenze.
