WebThe 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. WebThe Photoelectric Effect. The Photoelectric Effect shows that Plank's hypothesis, used to fit the Black Body data, is actually correct for EM radiation. Einstein went further and proposed, in 1905, that light was …
