Draw suitable graphs to show the variation of photoelectric current with collector plate potenetial for
a fixed fintensity but different frequencies `v_1>v_2>v_3` of radiation.

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.

Draw a plot showing the variation of photoelectric current versus the intensity of incident radiation on a given photosensitive surface.
