The graph between frequency of incident radiations and stopping potential for a given photosensitive material is as follows. What information can be obtained from the value of the intercept on the potential axis?

Options

  1. AWork function
  2. BKE of electrons
  3. CStopping potential
  4. DFrequency of photon

Correct answer

A. Work function

Step-by-step solution

Graph between frequency of incident radiation and stopping potential for a given photosensitive surface is shown below: Intercept on the potential axis = − W 0 e ∴ Work function, W 0 = e × Magnitude of intercept on the potential axis.
