Polaroid sunglasses reduce glare from a wet road most effectively because:
AReflected light from the road is largely polarised horizontally
BPolaroids randomly scatter incident light off the lens material
CSunglasses simply darken the field of view, like any tint
DPolaroids increase the intensity at certain critical angles
Answer & Solution
Correct answer: A. Reflected light from the road is largely polarised horizontally
Reflection from a horizontal surface (road) produces predominantly horizontal polarisation; Polaroids transmit only vertical, blocking glare.
