Given below are two statements : Statement I : Figure shows the variation of stopping potential with frequency (v) for the two photosensitive materials M ₁ and M ₂ . The slope gives value of h e , where h is Planck's constant, e is the charge of electron. Statement II : M ₂ will emit photoelectrons of greater kinetic energy for the incident radiation having same frequency. In the light of the above statements, choose

Options

  1. ABoth Statement I and Statement II are correct
  2. BStatement I is incorrect but Statement II is correct
  3. CBoth Statement I and Statement II are incorrect
  4. DStatement I is correct and Statement II is incorrect

Correct answer

D. Statement I is correct and Statement II is incorrect

Step-by-step solution

aligned & eV ₀= hv - & V ₀= h e v - e aligned M ₂ material has higher work function, so statement-(II) is incorrect.
