Question

In a photoelectric experiment anode potential is ploted against plate current.

A. A nd B will have different 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 equal frequencies
D. A and B will have equal intensities while B and C have different frequencies

Answer 1

Correct Answer - D
From the graph, it is clear that A and B have the same stopping potential and therefore the same frequency. Also, B and C have the same intensity.
