From the figure describing photoelectric effect we may infer correctly that

A

Na and Al bothh have the same threshold frequency

B

maximum kinetic energy for both the metals depend linearly on the frequency

C

the stopping potential are different for Na annd Al for the samme change in frequency

D

Al is a better photo sensitive material than Na

Text Solution

Verified by Experts

The correct Answer is:
B
The graph betweenn stopping potential and frequency is a straight line, so stopping potential and hence, maximum kinetic energy of photoelectrons depends linearly on the frequency.
