light is something which gives us the sense of sight, having dual nature, a kind of radiation, a energy, which shows many phenomenas like differaction, interference, reflaction, scattering etc etc
I am geting confused ( :confused: ) that what is the difference between photo-conductive and photo-voltic devices.
as boath devices depends on the intensity of light, boath depends on no of charge cariers,...
In boath cases there is movement of charge cariers , so there is a flow of current...
