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

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion

Step-by-step solution

Stopping potential is a measure of maximum kinetic energy of emitted photoelectron (e V₀=K_ ) and K_ depends upon the frequency of incident light but is independent of intensity.
