Answer:
In physics, polarization refers to the orientation of electric field vectors in an electromagnetic wave. When an electromagnetic wave passes through a transparent material such as glass, some of the light waves may be polarized, meaning their electric field vectors vibrate in only one plane or direction.
Polarization can be removed by certain methods such as by using a polarizing filter. A polarizing filter works by allowing only light waves of a particular orientation to pass through along its axis. Any other polarized light waves that are not aligned with the filter axis will be blocked, effectively removing their polarization. Another method involves changing the angle of incident light to a certain degree called Brewster's angle, which causes the reflected light to become polarized.
