T: Ta yaya za mu iya hana na'urar firikwensin daukar hoto mai yaɗuwa gano abubuwan bango na ƙarya a wajen kewayon ji?
A: A matsayin mataki na farko, ya kamata mu tabbatar ko asalin da aka gano ba daidai ba yana da siffa ta "mai haske mai yawa".
Abubuwan bango masu haske mai yawa na iya tsoma baki ga aikin na'urori masu auna hasken haske na hasken rana. Suna haifar da ƙaryar tunani, wanda ke haifar da kuskuren karanta na'urori masu auna hasken haske. Bugu da ƙari, abubuwan da ke nuna haske mai yawa na iya tsoma baki ga na'urori masu auna hasken haske da kuma na'urorin auna hasken haske na bango har zuwa wani lokaci.
