From photoelectric effect experiment, select the correct statement. (a) Photoelectric effect can be explained using wave theory of light. (b) The maximum kinetic energy of a photoelectron depends on the intensity of incident light. (c) The stopping potential depends only on the work function of the metal. (d) The saturation current increases as the intensity of incident light increases.

Answer: (d). (a) False: wave theory cannot explain threshold frequency or instant emission. (b) False: maximum KE depends on frequency, not intensity. (c) False: stopping potential depends on frequency and work function. (d) True: more photons per second give more electrons, so saturation current rises with intensity. So the answer is (d).
