Assertion : In the process of photoelectric emission , all the emitted photoelectrons have the same kinetic energy.
Reason : The photon transfers its whole energy to the electron of the atom in photoelectric effect.

A

If both assertion and reason are true and the reason is the correct explanation explanation of assertion.

B

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

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Only the photoelectrons emitted from the surface of the metal have maximum kinetic energy . Those emitted from inside the metal loses part of their energy in collision with the other atoms inside the metal.
