Re: NDT exam question
UV light means electromagnetic radiation from 200nm to 400nm wavelenght (under 200nm you have vacum UV).
Black light is comonly used to refer to the UVA (UV band A light), this is from 315nm to 400nm, wich is the used for the fluorescent tests (with the peak in 365nm, that is the wavelenght that allows the fluorescence fenomenum)
