Dual Nature Of Light Question 415

Question: In a photoelectric experiment, anode potential is plotted against plate current in figure. Then

Options:

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 equal intensities while A and C will have equal frequencies

D) B and C have equal intensities while A and B will have same frequencies

Show Answer

Answer:

Correct Answer: D

Solution:

[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.
