Question

In photoelectric effect experiment, show the variation of (a) photocurrent with collector plate potential for a given surface for different intensities of incident radiation. Do the curves meet at any point ? If so, why ? (b) photocurrent with intensity of radiation incident on a surface keeping the frequency and plate potential fixed.

How does Einstein's photoelectric equation explain the emission of electrons from a metal surface ? Explain briefly. Plot the variation of photocurrent with : (a) collector plate potential for different intensity of incident radiation, and (b) intensity of incident radiation.

How would the stopping potential for a given photosensitive surface change if (i) the frequency of the incident radiation were increased ? and (ii) the intensity of incident radiation were decreased ? Justify your answer.
