As I know, a black substance absorbs all light and a white substance reflects all light.
Can I say, in a black substance, the electrons are in a high energy state, compared to a white substance?
And how much light energy it can absorb? There has to be a limit to it, right?
So, shouldn't a black substance turn white after exposing to light for some period of time?
Thanks,
