Question

Light is propagated as a transverse wave. For this reason, sunglasses, ski goggles and camera lenses can restrict the vibration of light to specific directions. This is known as

Answer 1

Polerization is the anwser

Answer 2

This is known as polarization.

Step-by-step explanation:

Polarization is the phenomenon in which the vibrations of light are restricted in a particular direction, which is perpendicular to the direction of propagation of wave.

Tourmaline crystals work as a polarizer.

Polarization takes place only for transverse waves.
