Photoelectric effect gold leaf
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.
