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

Options

A $\mathrm{Na}$ and $\mathrm{Al}$ both have the same threshold frequency
BMaximum kinetic energy for both the metals depends linearly on the frequency
Cthe stopping potential are different for $\mathrm{Na}$ and $\mathrm{Al}$ for the same change in frequency
D $\mathrm{Al}$ is better photosensitive material than $\mathrm{Na}$

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.
