Bright sunlight is reflected from an icy pond. You look at the glare of the reflected light through polarized glasses. When you take the glasses off, rotate them 90∘, and look through one of the lenses again, the light you see becomes brighter. Explain why the light you see changes.

a) The glass blocks horizontally polarized light, and the light reflected from the icy pond is, in part, polarized horizontally.

b) The glass blocks horizontally polarized light, and the light reflected from the icy pond is, in part, polarized vertically.

c) The glass allows horizontally polarized light to pass, and the light reflected from the icy pond is, in part, polarized vertically.

d) The glass allows horizontally polarized light to pass, and the light reflected from the icy pond is, in part, polarized horizontally.

a.

Explanation:

(a) The glass blocks horizontally polarized light, and the light reflected from the icy pond is, in part, polarized horizontally.

Here, Option A situation is before rotating the axis of glass. Option D is for situation after rotating the axis.

Polarized glasses provide superior glare protection - especially on water. The polarised lenses have a special filter that block this types of intense reflected light. reducing glare and discomfort.
