WebSolution. Photoelectric can be only explained by assuming that light is made up of particle not wave because. There is no time lag b/w incident of radiation and ejection of electrons. If light were a wave than electrons will take some time to come out from metal because light wave of same energy would be distributed over large number of electrons. WebSep 12, 2024 · The 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.

Web(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.
