Which of the following statement is correct? (a) The photocurrent increases with intensity of light (b) The stopping potential increases with increase of incident light (c) The current in photocell increases with increasing frequency (d) The photocurrent is proportional to the applied voltage.

Answer: (a). (a) True: photocurrent ∝ intensity. (b) False: stopping potential V₀ = (hν - φ)/e does not depend on intensity. (c) False: saturation current does not increase with frequency. (d) False: current saturates, it is not proportional to voltage. So the answer is (a).

Which of the following statement is correct?

Show answer and solution

Answer: (a)

(a) True: photocurrent $\propto$ intensity.
(b) False: stopping potential $V_0 = (h\nu - \phi)/e$ does not depend on intensity.
(c) False: saturation current does not increase with frequency. (d) False: current saturates, it is not proportional to voltage.
So the answer is (a).
