Polarisation of light proves:
Polarisation of light proves:
Updated On: Jul 28, 2022
- corpuscular nature of light
- quantum nature of light
- transverse wave nature of light
- longitudinal wave nature of light
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Polarisation explain the wave nature of light, as light wave are polarised in a particular plane. The longitudinal waves cannot to be polarised. So, transverse wave can only be polarised. Hence, polarisation of light proves the transverse nature of light.

Concepts Used:
Polarisation
Light travels in form of transverse EM waves. The underlying oscillation is along directions perpendicular to the propagation direction, in this example, oscillating electric and magnetic fields. Process of restricting the vibration of light waves to one direction is known as Polarisation.
Types of Polarisation:
There are three types of polarisation such as:
- Linear Polarisation in the electric field of light is limited to one single plane that is along the direction of propagation.
- Elliptical Polarisation: In this, both the phase difference and amplitude between the two linear components are not equal.
- Circular Polarisation: The electric field of light follows a circular propagation. The two linear components that exist in the electric field are the same amplitudes but have different phase differences.
Methods of Polarisation of Light:
The few methods of polarisation of Light are:
- Polarization by dispersing
- Polarization by Reflection
- Polarization by Refraction
- Polarization By Transfer
