A radiation falls on a photosensitive material. State how the following changes affect the emitted photoelectrons:
(i) increase in intensity of incident radiation.
(ii) increase in the frequency of incident radiation.

(i) Increase in intensity increases the number of emitted photoelectrons (or photoelectric current
increases).
(ii) Increase in frequency of incident radiation increases the kinetic energy (K.Emax) of the photoelectrons
emitted.
