Question

The phenomenon of polarization shows that light has ________ nature.

• A. Particle
• B. Transverse
• C. Longitudinal
• D. Dual

Answer 1

The correct option is B

Transverse

Explanation for the correct option:

In case of option B,

1. Polarization explain the wave nature of light, as light wave are polarized in a particular plane.
2. Electromagnetic waves with a single plane of vibration are known as polarized light waves.
3. It is clear that light is a transverse wave because it shows polarization.
4. The fact that light waves are transverse means that their oscillation direction is perpendicular to their direction of propagation.
5. The fact that an oscillation can occur in more than one direction is implied by polarization.
6. A transverse wave can be polarized since there are several configurations perpendicular to the direction of propagation.

Explanation for incorrect options:

In case of option A,

1. Polarization can not explain particle nature of light.

In case of option C,

1. Whereas longitudinal waves like sound can not be polarized.

In case of option D,

1. Polarization can explain only wave nature of light. it can not explain particle nature of light.
2. Thus it can not explain dual nature of light.

Hence, option B is the correct answer.
