A) increases with increase in frequency of incident photon
B) decreases with increase in frequency of incident photon
C) does not depend on the frequency of photon but depends only on the intensity of incident light
D) depends both on intensity and frequency of the incident photon
Correct Answer: C
Solution :
By increase in frequency energy of photon can be increased but number of photons will be unaffected. To increase the photo current, the number of electrons emitted per second should be increased. This can be done by increasing the incident intensity.
