Question

The number of photo electrons emitted for light of frequency $v$ (higher than the threshold frequency $v_0$) is depends on

• A. $v_0$
• B. intensity of light
• C. $v$
• D. $v$ - $v_0$

Answer 1

The correct option is B intensity of light

The number of photoelectrons decide the photocurrent. Assuming that the number of electrons emitted depends on the number of incident photons, the number of photoelectrons depend on the intensity of light.
