Statement-1: The photoelectrons produced by a monochromatic light beam incident on a metal surface have a spread in their kinetic energies.
Statement-2: The work function of the metal varies as a function of depth form the surface.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
B. if both assertion and reason are true but reason is not the correct expalanation of the assertion
C. if assertion is true , but reason is false
D. both assertion and reason are false statements.

Answer

C

Explanation

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