Two pieces of Polaroid are held against the light.

Can you look through them by themselves?

In longitudinal waves the vibrations of the medium are parallel to wave propagation and thus the vibrations are exactly similar in all planes drawn through the direction of propagation and hence we can say that the longitudinal waves are practically symmetrical about the direction of propagation.
In transverse waves the particles of medium vibrates perpendicular to the direction of wave propagation and thus are not symmetrical about direction of propagation.
Light is electromagnetic wave with variation of electric and magnetic field perpendicular to each other and both are perpendicular to the direction of propagation of light and ...
