The figure VSAQ 29 shows a plot of three curves a,b,c, showing the variation of photocurrent in collector plate potential for three different intensities I_1 , I_2 and I_3 having frequencies v_1 , v_2 and v_3 respectively incident on a photosensitive surface. Point out the two curves for which the incident raidations have the same frequency but different intensities.
