# Polarization of Light

## What is Polarisation of Light? What is polarization? Define polarization.

Polarized meaning or Polarized meaning: Polarization definition or Polarization definition: Light waves travel through the space to reach us and because of Earth’s magnetic field, it becomes an Electromagnetic wave. These light waves are transverse. It exhibits the phenomenon of reflection, refraction, interference, diffraction, double refraction, and polarization. Light is the interaction of electric and magnetic fields traveling through space. The electric and magnetic vibrations of a light wave occur perpendicularly to each other. The electric field moves in one direction and magnetic in another, though always perpendicularly.

Types of Polarization of Light

Depending upon transverse and longitudinal wave movement, the polarization of light is classified into three types.

1. Linear polarization: Linearly polarized light wave means that the electric field vibrates in a certain linear direction perpendicular to the wave axis, and the magnetic field vibrates in a direction which is perpendicular to both, the advancement axis and direction of the electric field.
2. Circular polarization: It is the type of polarization in which at every point, the electromagnetic field has a constant magnitude, but its direction rotates with a constant value in a plane perpendicular to the direction of the wave.
3. Elliptical polarization: It is the type of polarization where the tip of the electric field vector defines an ellipse in any fixed plane traversing, as well as is normal to the direction of propagation.
