In a photoelectric experiment anode potential is ploted againest plate currect.

A

`A` and `B` will have different intensities while `B` and `C` will have different frequencies

B

`B` and `C` will have different intensities while `A` and `C` will have different frequencies

C

`A` and `B` will have different intensities while `A` and `C` will have different frequencies

D

`B` and `B` will have equal intensities while `A` and `B` will have different frequencies

Text Solution

Verified by Experts

The correct Answer is:
D
From the graph it is clear that `A` and `B` have the same stopping potential and therefore, the sure frequency Also `B` and `C` have the same intensity
