Question

Which of the following phenomena can not be explained by wave theory of light ?

(1) Reflection of light

(2) Diffraction of light

(3) Refraction of light

(4) Compton effect

Answer 1

Correct option is : (4) Compton effect

Compton effect refers to scattering of a photon by free electrons. This phenomenon provides an evidence for particle nature of light.

Answer 2

The correct option is: (4) Compton effect

Explanation:

The Compton effect refers to the scattering of X-rays or gamma rays by electrons, resulting in a change in the wavelength of the scattered light. This phenomenon can only be explained by the particle nature of light (photon theory), as it involves the transfer of energy and momentum between photons and electrons.
