The figure shows a plot of three curves a, b, c showing the variation of photocurrent vs. collector plate potential for three different intensities I1 , I2 and I3 having frequencies n1 , n2 and n3 respectively incident on a photosenitive surface. Point out the two curves for which the incident radiations have same frequency but different intensities. |

Answer» Curves a and b have different intensities but same stopping potential, so curves ‘a’ and ‘b’ have same frequency but different intensities. |
