Question

Polarized sunglasses work by A. blocking light waves that vibrate in one plane. B. gradually refracting light as it passes through the lenses. C. bending light as it passes from air into the lenses. D. reflecting most of the light that strikes the sunglasses.

Answer 1

None of the choices is correct, but 'A' is kind of on the right track. A polarizing filter PASSES only the light that vibrates in one plane or close to it, and reflects or absorbs all the light that doesn't.

Answer 2

Answer: Polarized sunglasses work by A. blocking light waves that vibrate in one plane.

Explanation:  

The photons from Sun vibrate in all directions. When sunlight strikes polarized sunglasses, the orientation of the polarized filter is such that it blocks the radiations in a particular direction and allowing in other thereby reducing the amount of reflected light in that direction. This reduces the visibility and causes glare.

Thus, correct option is Polarized sunglasses work by A. blocking light waves that vibrate in one plane.
