Expert Answer:
It is that wave motion in which the particles of the medium through which the wave is travelling vibrate in a direction parallel to the direction of the motion of the wave.
In the figure, the wave is travelling from left to right, and the particles of the medium vibrate in the horizontal direction simple harmonically. It represents the longitudinal wave motion.
For their propagation, the medium must possess:
(i) elasticity
(ii) inertia
(iii) absence of frictional resistance.

- A narrow sound pulse (for example, a short pip by a whistle) is sent across a medium. (i) Does the pulse have a definite (a) wavelength, (b) frequency, (c) speed of propagation? (ii) If the pulse rate is 1 after every 20s (i.e the whistle is blown for a split second after every 20s), is the frequency of the note produced by the whistle equal to 1/20 = 0.05 Hz?
