What is polarization of light?

PhysicsOptics

Quick Answer

Polarization is the orientation of light’s oscillating electric field. It is a property of transverse electromagnetic waves.

The Full Story

Light waves have electric and magnetic fields that oscillate perpendicular to the direction of travel, and polarization describes the direction of those oscillations. Sunlight is usually unpolarized, meaning its polarization directions are mixed, but reflection, scattering, and filters can produce polarized light. Polarizing sunglasses reduce glare by blocking certain orientations of reflected light. Polarization is also used in LCD screens, photography, and many physics experiments.
