Photons of energy 6 eV are incident on a metal surface whose work function is 4 eV. The minimum kinetic energy of the emitted photo-electrons will be
Options
(a) 0 eV
(b) 1 eV
(c) 2 eV
(d) 10 eV
Correct Answer:
0 eV
Explanation:
Minimum kinetic energy is always zero, when the photon loses its energy by collision.
