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. WebFeb 2, 2024 · The photoelectric effect should occur for any light, regardless of frequency or wavelength. There should be a delay on the order of seconds between the radiation’s contact with the metal and the initial release of photoelectrons. The Experimental Result
