#### 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 I_{1}, I_{2}and I_{3} having frequencies *v*_{1}, *v*_{2} and *v*_{3} 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.

Is there an error in this question or solution?
