Vedclass · Answer

$(A)$ Incorrect. The stopping potential $(V_0)$ depends on both the frequency of incident light ($
u$) and the work function ($\Phi$) of the metal, given by $eV_0 = h
u - \Phi$.$(B)$ Correct. The saturation current is directly proportional to the intensity of the incident light because intensity determines the number of photons, and thus the number of photoelectrons emitted per second.$(C)$ Incorrect. The maximum kinetic energy $(K_{max})$ of a photoelectron depends only on the frequency of the incident light and the work function of the metal; it is independent of the intensity of light.$(D)$ Incorrect. The photoelectric effect cannot be explained by the wave theory of light; it requires Einstein's particle theory (photon model) to explain the instantaneous emission and frequency dependence.
