question

(a) plot a graph showing the variation of photoelectric current with collector plate potential for different frequencies but of same intensity of incident radiation.

(b) green and blue light of same intensity are incident separately on the same photosensitive surface. if both of these cause photoelectric emission, which one will emit photoelectrons  (i) having greater kinetic energy and (ii) producing larger photocurrent? justify your answer.
