Options

  1. AWhich two of the following five physical parameters have the same dimensions? (a) energy density (b) refractive index
  2. BWhich two of the following five physical parameters have the same dimensions? (a) energy density (b) refractive index
  3. CWhich two of the following five physical parameters have the same dimensions? (a) energy density (b) refractive index
  4. DWhich two of the following five physical parameters have the same dimensions? (a) energy density (b) refractive index

Correct answer

C. Which two of the following five physical parameters have the same dimensions? (a) energy density (b) refractive index

Step-by-step solution

Given lights are of same wavelength and stopping potential is independent on intensity. Hence stopping potential will remain same. Intensity I2>\mathrm{I}_2>\mathrm{I}1_1, hence saturation current corresponding to I2\mathrm{I}_2 will be greater than that corresponding to I1\mathrm{I}_1.
