What is sound and how does it travel? ... Sound or pressure waves are made up of compressions and rarefactions. Compression happens when particles are forced, or pressed, together. Rarefaction is just the opposite, it occurs when particles are given extra space and allowed to expand.

As the tuning fork goes on vibrating, waves consisting of alternate compressions and rarefactions spread in air as shown in fig (d). The direction of motion of the sound waves is same as that of air particles, hence they are classified ... The longitudinal waves travel in the form of compressions and rarefactions.

In physics, sound is the transfer of energy resulting from the successive compressions and rarefactions of a material medium because of a disturbance in that medium. Compression refers to the instances when the disturbance moves the particles of the medium closer together than they normally are during equilibrium.

Hint for Question 12: When one has a sound wave there are alternating compressions and rarefactions. In a rush of wind the molecules have varying position and a velocity, and energy is being ... Correct Answer to Question 20: When a wave hits a wall where the rope is tied down it stretches the rope more than normally.
