Question

In a photoelectric experiment, anode potential is plotted against plate current. Select the correct statement from the following

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

Answer 1

The correct option is A A and B will have different intensities while B and C will have different frequencies

Stopping potential only depends on frequency. Stopping potential is the point where the graph cuts X axis. that means A and B have same frequency different from C.

Saturated photocurrent depends on the intensity of the light.

So B and C have same intensity different from that of A.
