Assertion: The photoelectrons produced by a monochromatic light beam incident on a metal surface, have a spread in their kinetic energies. Reason : The work function of the metal varies as a function of depth from the surface.

Options

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

Correct answer

C. If assertion is true, but reason is false

Step-by-step solution

Statement is correct, but the work function only depends on the photoelectric metal.
