Assertion : The photoelectrons produced ...

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

A

If both assertion and 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 explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
`KE_("max")=hv =phi`
`0leKE_("Photoelectrons") leKE_("max")`, Also `phi` of material is constant.
