With respect to electromegnetic theory of light, the photoelectric effect is best explained by statement

Options

A. Light waves carry energy and when light is incident on the metallic surface, the energy absorbed by the metal may somehow concentrate on individual electrons and reappear as their kinetic energy when ejected
B. Particles of light (photons) collide with the metal and the electrons take this energy and may eject
C. When light waves fall on a metallic surface, the stability of atoms is disturbed and the electrons come out to make the system stable
D. none of the above

Answer

A

Explanation

Option (a) correctly explains the photoelectric effect on the basis of electromagnetic theory. Its correct explanation is given by Quantum theory of light.
