Assertion : Photoelectric effect is most readily shown by ceasium metal.
Reason : Photon have easiest access to the surface of ceasium metal .

A

if both assertion and reason are correct and reason is correct explanation for assertion .

B

If both assertion and reason are correct but reason in not correct explanation for assertion.

C

If assertion is correct but reason is incorrect.

D

If both assertion and reason are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
C
Correct reason. In ceasium, the electrons are most loosely held on the surface of the atom due to very small ionisation energy.
