Question:

A graph for variation of photo current with anode potential is given for different intensities of incident radiation:

Choose the correct order of anode intensities.

Options:

$l_1> l_2, l_3$

$l_1= l_2=l_3$

$l_1 < l_2 < l_3$

$l_1< l_2> l_3$

Correct Answer:

$l_1 < l_2 < l_3$

Explanation:

The correct answer is option (3) : $l_1 < l_2 < l_3$

Photo current is directly proportional to intensity of incident light.
