WebAug 9, 2024 · The photoelectric effect is the process in which electromagnetic radiation ejects electrons from a material. Einstein proposed photons to be quanta of electromagnetic radiation having energy is the frequency of the radiation. All electromagnetic radiation is composed of photons. Webequations. Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy ( Kmax) of the photoelectrons to the frequency of the absorbed photons ( f) and the threshold frequency ( f0) of the photoemissive surface. Kmax = h ( f − f0)
