Vedclass · Answer

(A) The photoelectric effect is the emission of photoelectrons from a clean metal surface due to incident light whose frequency is greater than a threshold frequency.The photoelectric effect supports the particle theory of light because it shows that the energy required to release electrons from a metal is dependent upon the frequency of the light,and not the intensity.Therefore,light behaves as a stream of particles (photons) in this phenomenon,confirming the particle-like behavior of light.
