Question

What of the following statements about polarization is wrong? (A) Longitudinal waves do not have polarization. (B) After going through a polaroid, natural light will become polarized. (C) One cannot transfer vertically polarized light into horizontally polarized light with polaroid filters. (D) Polaroid sunglasses can reduce horizontally polarized light reflected off flat surfaces.

Answer 1

Answer C is the incorrect statement about polarization.

Following are the points for the justification:

1. Answer A is correct since

Longitudinal waves can't be polarised because their particles vibrate in the same direction that the wave travels.

2. Answer B is correct since

Natural light is polarized in the passage through a number of materials, the most common being polaroid.

4. Answer D is correct since

When you are wearing polarized sunglasses, the surface blocks the glare by filtering out the horizontal light waves that don’t fit through the chemical laminate pattern.
