Question
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, I2and I3 having frequencies v1, v2 and v3 respectively incident of a photosensitive surface.
Point out the two curves for which the incident radiations have same frequency but different intensities.
Solution
Curves a and b have the same frequency but different intensities.
