How do polarized sunglasses work?

They bend light as it passes from air into the lenses.

They reflect most of the light that strikes the lenses.

They use filters to transmit light waves that vibrate in one plane.

They gradually refract light as it passes through the lenses.

Answer: The correct answer is "They use filters to transmit light waves that vibrate in one plane".

Explanation:

In unpolarized light, the light wave vibrates in more than one plane. The rays coming from the sun are unpolarized light.

In polarized light, the light wave vibrate in the single plane.

Polarized sunglasses have polarized filter. Polarized filter is able to polarize light due to the chemical composition of the material filter. Polarized sunglasses decreases the intensity of the sunlight.

Polarized sunglasses use filters to transmit light waves that vibrate in one plane. In this way, the unpolarized light becomes polarized light by using polarized sunglasses.

They use "polarizing" filters, which transmit light waves that vibrate in one plane, and absorb light waves that vibrate in the other planes.
