In case of photoelectric effect

WebIn 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. This process is termed as the photoelectric effect or ... WebINTRODUCTION. The energy quantization of electromagnetic radiation in general, and of light in particular, is expressed in the famous relation. (1) E = h f, where E is the energy of the radiation, f is its frequency, and h is Planck's constant (6.63×10 -34 Js). The notion of light quantization was first introduced by Planck.
