Vedclass · Answer

(A) The classical electromagnetic theory of light treats light as a continuous wave. According to this theory,the energy of the wave depends on its intensity (amplitude). However,experimental observations of the photoelectric effect show that the emission of electrons depends on the frequency of the incident light,not its intensity. Furthermore,the emission is instantaneous,which contradicts the classical prediction of a time lag for energy absorption. Therefore,the electromagnetic theory of light failed to explain the photoelectric effect.
