Sketch the graphs, showing the variation of stopping potential `V_s` with frequency v of the incident radiations for two photosensitive materials A and B having threshold frequencies `v_0gtv'_0` respectively.   (i) which of the two metals A or B has higher work function?  (ii) What information do you get from the slope of the graphs?  (iii) What does the value of the intercept of graph A on the potential axis represent?
