$(b)$ What is meant by a transverse wave? Give an example.
(N/A) density-distance graph represents a longitudinal wave,as longitudinal waves involve variations in density and pressure of the medium.
$(b)$ $A$ transverse wave is a wave in which the particles of the medium vibrate in a direction perpendicular to the direction of wave propagation. An example of a transverse wave is the wave produced in a vibrating string or light waves.
