Answer 1

Hey !

Option (b) is the answer :

Infra-Red waves, Light Waves, Ultra-Violet Waves.

Explanation:

For a transverse Wave, the Oscillations are perpendicular to the direction of the wave in which it is Propogating/moving.

In Air, Sound waves are longitudinal waves (or) Compression Waves as the oscilations are parallel to the direction of the wave in which it is moving.

Except in Option -(b) Sound waves option exist in all of the given options.
