What is polarization of waves?
0:02
Definition: Polarization of waves is the
0:05
restriction of the vibrations of a
0:07
transverse wave to a single plane.
0:10
Explanation: Only transverse waves like
0:12
light waves can be polarized since their
0:15
vibrations are perpendicular to the
0:18
direction of wave travel. Normally,
0:21
transverse waves vibrate in many random
0:23
directions. Polarization filters these
0:26
vibrations so that they all align in
0:29
just one direction. Longitudinal waves
0:32
like sound cannot be polarized because
0:35
their vibrations are along the direction
0:37
of motion. Imagine, think of shaking a
0:40
rope tied to a wall. If you shake it up
0:42
and down, the wave is vertical. If you
0:45
shake it side to side, it's horizontal.
0:48
But if you pass the rope through a
0:50
narrow slot that only allows vertical
0:52
vibrations, you've polarized the wave.

In simple terms, polarization makes
0:58
waves vibrate in just
