Question

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

• 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 energy when ejected 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 1

The correct option is 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

According to the wave theory of light, as wave carries energy it was suggested that when the wave strikes on the electron, electron get the energy or gather energy and comes out of the metal surface and the extra energy apart from the energy required to pass the threshold energy appears as the kinetic energy of the electron.
