CBSE · Class 12 · Physics · Dual Nature of Radiation and MatterIn the photoelectric effect, the stopping potential depends upon:
Step-by-Step Solution
Stopping potential $V_0$ is given by $eV_0 = K_{\max} = h\nu - \phi_0$. Thus, it depends upon the frequency of the incident radiation and the nature of the metal surface (work function), but it is independent of the intensity of incident radiation.
