प्रश्न

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 v1v2 and v3 respectively incident of a photosensitive surface.

Point out the two curves for which the incident radiations have same frequency but different intensities.

उत्तर

Curves a and b have the same frequency but different intensities.
