A metal surface is exposed to solar radiations:
(1) The emitted electrons have energy less than a maximum value of energy depending upon frequency of incident radiations
(2) The emitted electrons have energy less than maximum value of energy depending upon intensity of incident radiation
(3) The emitted electrons have energy equal to energy of photos of incident light
(4) The emitted electrons have zero energy
Ans: The emitted electrons have energy less than a maximum value of energy depending upon frequency of incident radiations
