Q.
The number of photo electrons emitted for light of a frequency $v$ (higher than the threshold frequency $v_0) $ is proportional to
AIPMTAIPMT 2009Dual Nature of Radiation and Matter
Solution:
The number of photoelectrons decide the photocurrent. Assuming that the number of electrons emitted depends on the number of photons incident, the number of photoelectrons depend on the intensity of light.
