WebAnswer. The photoelectric effect refers to the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light. Energy contained within the incident light is absorbed by electrons within the metal, giving the electrons sufficient energy to be 'knocked' out of, that is, emitted from, the surface of the ... WebA photon particle is the tiny blob of pure energy. In the photoelectric effect, the electron is attacked by a wandering blob of energy. Hence electron gets excited and further, it breaks its bond with the atom to which it is held. Under suitable circumstances, we can use light to push electrons and free them from the surface of a solid.
