Q59 / 60 · IAT (IISER) 2022 · Physics

The figures in the options show the photocurrent $J$ of a photoelectric material versus the frequency $f$ of an incident light beam. The light beam can have three different intensities $I_1, I_2, I_3$, with $I_3 \gt I_2 \gt I_1$. Which of the options is correct?

A
B
C
Correct answer
D

Hence, the correct answer is option: 'D'.
