MCQ
Which of the following statement is correct?
  • ✓
    Photo$-$current increases with intensity of light
  • B
    Photo$-$current is proportional to the applied voltage
  • C
    Current in photocell increases with increasing frequency
  • D
    Stopping potential increases with increase of incident light
✓

Answer

Correct option: A.
Photo$-$current increases with intensity of light
More is the intensity of incident radiation, more is the umber of photons and thus more is the number of photo electrons emitted. This results in the increase in the photo$-$current.

In a historical experiment to determine Planck's constant, a metal surface was irradiated with light of different wavelengths. The emitted photoelectron energies were measured by applying a stopping potential. The relevant data for the wavelength $(\lambda)$ of incident light and the corresponding stopping potential $\left(V_0\right)$ are given below :

$\lambda(\mu \mathrm{m})$ $V_0$ (Volt)
