From figure describing photoelectric effect we may infer correctly that Frequency

A

Na and Al both have the same threshold frequency

B

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

C

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

D

Al is a better photo sensitive material than Na.

Text Solution

Verified by Experts

The correct Answer is:
