Question

Assertion (A): On increasing the intensity of incident light of frequency \( v(> v_0) \) on a photosensitive surface, the photocurrent increases. Reason (R): The stopping potential for a photosensitive surface increases with increase of frequency \( v(> v_0) \) of incident light.

• A. Both A and R are true and R explains A
• B. Both A and R are true but R does not explain A
• C. A is true but R is false
• D. A is false and R is false

Hint:

Intensity controls the number of emitted electrons and hence photocurrent. Frequency controls the energy of emitted electrons and hence stopping potential.

Answer 1

The Correct Option is B
