Question

The graph between frequency $(v)$ and stopping potential ( $V_0$ ) is found to be a straight line which is not passing through the origin. This graph shows that, the stopping potential $V_0$ varies linearly with the frequency of incident radiation for a given photosensitive material. There exist a certain minimum cut-off frequency $\left(v_0\right)$ for which the stopping potential is zero. In photoelectric effect, stopping potential depends on

Professor PC Thomas Classes · Answer

(d): The stopping potential depends on frequency of incident light and the nature of the emitter material. For a given frequency of incident light, it is independent of its intensity.
