Question

select the correct answer.
paul is driving his car on a sunny afternoon. which glasses should he ideally wear while driving?
a. glasses that can block off the polarized light
b. glasses that can block vertically polarized light
c. glasses that can block horizontally polarized light
d. glasses that can block light incident at 45°
e. glasses that can pass all the light as it is

Explanation:

When driving on a sunny afternoon, the glare from roads (like from water or asphalt) is horizontally polarized light. Polarized sunglasses are designed to block horizontally polarized light to reduce glare, improving visibility and reducing eye strain. Option A is incorrect as blocking all polarized light isn't practical or needed. Option B is wrong because vertical polarization isn't the source of glare here. Option D is not relevant to reducing glare from road surfaces. Option E would not reduce glare at all. So the correct choice is the one that blocks horizontally polarized light.

Answer:

C. glasses that can block horizontally polarized light
