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. shanghai bobby pedigreeWebPredictions based on light as a wave. To explain the photoelectric effect, 19th-century physicists theorized that the oscillating electric field of the incoming light wave was heating the electrons and causing them to vibrate, eventually freeing them from the metal surface.
