When an electron moves to lower energy state it emits a photon, now if a photon is absorbed by an electron does the electron move back to the higher energy state. (I don't think that 'energy state' is the right term) If so how hard is it to put the photon into the electron? I assume that it not an everyday occurrence as then all electron would be endless moving up.
