Question

what does a polaroid consists of ? Using a simple polaroid show that light waves are transverse in nature.

Answer 1

A Polaroid consists of Nicole prims arranged such as to allow the fields to vibrate only in one plane.

Thus, if we put a Polaroid in the way of a ray.and then another Polaroid in the transmitted way such that their axis perpendicular to each other then no ray passes.
Proving that vibrations are perpendicular to the direction of propagation.Light has transverse nature.
