The graph shows the variation of photocurrent for a photosensitive metal

Question 15:The graph shows the variation of photocurrent for a photosensitive metal

(a)What does X and A on the horizontal axis represent? (b)Draw this graph for three different values of frequencies of incident radiation ʋ1, ʋ 2 and ʋ 3 (ʋ 3>ʋ 2>ʋ1) for the same intensity. (c) Draw this graph for three different values of intensities of incident radiation I1, I2 and I3 (I3> I2>I1) having the same frequency.

The correct answer is -a)A - cut off or stopping potential X - anode potential
