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. Webin photoelectric experiments we are always interested in finding two things one is counting the number of electrons coming out per second something that we discussed in our previous video and the second which we'll discuss in this video is calculating or measuring the maximum kinetic energy of the electrons so the question is how do you find what …
