The number of photo electrons emitted for light of a frequency v (higher than the threshold frequency v₀) is proportional to:

Options

(a) Threshold frequency (v₀)
(b) Intensity of light
(c) Frequency of light (v)
(d) v – v₀

Correct Answer:

Intensity of light

Explanation:

The no. of photoelectrons emitted is proportional to the intensity of incident light. Saturation current ∞ intensity
