The figure shows the variation of photocurrent with anode potential for a photosensitve surface for three different radiations. Let l_a, l_b and l_c be the curves a, b and c, respectively (a) f_a = f_b and l_a != l_b (b) f_a = f_c and l_a = l_c (c ) f_a = f_b and l_a = l_b (d) f_b = f_c and l_b = l_c
