Question
Plot a graph showing the variation of stopping potential with the frequency of incident radiation for two different photosensitive materials having work functions W1 and W2 (W1 > W2). On what factors does the (i) slope and (ii) intercept of the lines depend?

Solution
(i) The slope of the graph is content and equals to`(h/e)`. Therefore, the slope does not depend on any factor.
(ii) The intercept of the lines depends on the work function ‘’`phi` of the metals.
