In photoelectric effect, the photocurrent (a) decreases with increase in frequency of incident photon. (b) increases 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 incident radiation.

Answer: (c). Each photon ejects at most one electron, so photocurrent ∝ number of photons per second ∝ intensity. Frequency (above ν₀) only changes the energy of each electron, Kmax = hν - φ, not their number. So the answer is (c): photocurrent depends only on intensity.

In photoelectric effect, the photocurrent

Show answer and solution

Answer: (c)

Each photon ejects at most one electron, so photocurrent $\propto$ number of photons per second $\propto$ intensity.
Frequency (above $\nu_0$ ) only changes the energy of each electron, $K_{max} = h\nu - \phi$ , not their number.
So the answer is (c): photocurrent depends only on intensity.
