What does polarizing light do?
A
Blocks light
B
Causes light to travel in only one plane
C
Reduces the amount of light
D
Looks cool
Explanation: 

Detailed explanation-1: -Polarized waves are light waves in which the vibrations occur in a single plane. Plane polarized light consists of waves in which the direction of vibration is the same for all waves. In the image above, you can see that a plane polarized light vibrates on only one plane.

Detailed explanation-2: -In plane-polarized light the component electric field oscillates as in ordinary light, except that the direction of oscillation is contained within a single plane. Likewise, the component magnetic field oscillates within a plane, the planes in question being perpendicular to each other.

Detailed explanation-3: -Most light sources are unpolarized. The electric field is vibrating in many directions; all perpendicular to the direction of propagation. Polarized light is unique in that it vibrates mostly in one direction. Any direction is possible as long as it’s perpendicular to the propagation, be it…
