From the figure describing photoelectric effect, we may infer correctly that

Options

  1. ANa and Al both have the same threshold frequency
  2. BMaximum kinetic energy for both the metals depends linearly on the frequency
  3. Cthe stopping potential are different for Na and Al for the same change in frequency
  4. DAl is better photosensitive material than Na

Correct answer

B. Maximum kinetic energy for both the metals depends linearly on the frequency

Step-by-step solution

The graph between stopping potential and frequency is a straight line, so stoppingpotential and hence maximum kinetic energy of the photoelectrons depends linearly on the frequency.
