Question 27: Dual Nature of Matter and Radiation

Question

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

Accepted Answer

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

Answer

Na and Al both have the same threshold frequency

Answer

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

Answer

the stopping potential are different for Na and Al for the same change in frequency

Answer

Al is better photosensitive material than Na
