In photoelectric effect, the photocurrent

MCQ

A
Increases with increasing frequency of incident photon.
B
Decreases with increasing frequency of incident photon
✓
Does not depend on the frequency of photon
D
Depends both on intensity and frequency of the incident photon

✓

Answer

Correct option: C.

Does not depend on the frequency of photon

c
When intensity of incident photon increases number of electrons emitted from the surface increases due to which current increases. Frequency of incident photon only limits the maximum kinetic energy of the photoelectron emitted and so the current is independent of frequency of photon.
