Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization . There are a variety of methods of polarizing light.

3D animations explaining circularly polarized, linearly polarized, and unpolarized electromagnetic waves.
Student experiment: Using polarising filters to observe polarisation effects. Provide each student with two Polaroid filters. Ask them to look through them at light sources (a lamp, the sky, (particularly at 90 ° to the Sun), etc.). Try one filter, then two. Rotate one relative to the other.
The polarization of light can be explained by the theory that light acts like transverse waves. Light vibrating parallel to some part of the polarizing crystal can pass through it. But light vibrating at a different angle is stopped by the crystal.
