Question

The transverse nature of light is shown by

• A. Interference of light
• B. Refraction of light
• C. Polarization of light
• D. Dispersion of light

Answer 1

The correct option is C

Polarization of light

Explanation of the correct option:

Polarization of light:

1. It is the phenomenon due to which the vibrations of light are restricted in a particular plane.
2. Polarized waves are the waves that have vibrations in only one plane and the process by which an unpolarized light is converted to polarized light is known as polarization.
3. When an unpolarized light passes through a tourmaline crystal, out of all the vibrations which are symmetrical about the direction of the propagation, only those that pass through it which are parallel to its crystallographic axis.

Explanation of the incorrect options:

1. Option (A)
   Interference of light is the phenomenon of non-uniform distribution of energy in the medium due to the superposition of two light waves.
2. Option (B)
   Refraction of light is the phenomenon of the change in the path of light as it goes from one medium to another. It usually occurs in lenses.
3. Option (D)
   Dispersion of light is the phenomenon of splitting up white light into its constituent colors.

Hence, option (C) is correct.
