WebbThis could not be explained as Maxwell’s electromagnetic theory (which Hertz proved correct) predicted that the kinetic energy should be only dependent on light intensity (not frequency). The resolution would only come a few years later by Einstein when he would provide an explanation of the photoelectric effect. Webb(a)Wave nature of radiation cannot explain the photo electric effects because of : (i) The immediate ejection of photo electrons (ii) The presence of threshold frequency for a metal surface. (iii) The fact that kinetic energy of the emitted electrons is independent of the intensity of light and depends upon its frequency. Webbthe electron will not be released from the metal. Besides this finding, Einstein's theory of the photoelectric effect was notable because it helped pave the way for the wave – particle duality interpretation of light and prompted further development in the field of wave –mechanics.

"WebbEinstein’s Theory of Photoelectric Effect. According to Einstein, the experimental results of photoelectric effect can be explained by applying the quantum theory of light. He assumed that light of frequency f contain packets or quanta of energy E = hf. On this basis, light consists of particles, and these are called photons. " - Theory of photoelectric effect

WebbThe photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics.
