Question

Light incident on a glass sheet is partly reflected and partly refracted. How is the reflected ray different from the refracted ray?

The refracted ray is unpolarized whereas the reflected ray is horizontally polarized.

The refracted ray is unpolarized whereas the reflected ray is vertically polarized.

The refracted ray is horizontally polarized whereas the reflected ray is
unpolarized.

The refracted ray is vertically polarized whereas the reflected ray is unpolarized.

The refracted ray is vertically polarized whereas the reflected ray is horizontally polarized.

Answer 1

Answer: The refracted ray is unpolarized whereas the reflected ray is vertically polarized.
 Many light sources like the sun produce waves which are polarized ( randomly). Light which is said to be unpolarized is made up of many waves having all possible directions of polarization.
