Assertion: Stopping potential depends upon the frequency of incident light but is independent of the intensity of the light. Reason : The maximum kinetic energy of the photoelectrons is proportional to stopping potential.

Options:

Answer:

Solution:

Stopping potential is a measure of maximum kinetic energy of emitted photoelectron $(e V_{0} = K_{m a x})$ and $K_{m a x}$ depends upon the frequency of incident light but is independent of intensity.
