What is the general name of the waves consisting of:
(a) compressions and rarefactions?
(b) crests and troughs?

Write the name of the wave which propagates in terms of compressions and rarefactions.

Define wave motion in which compression and rarefaction occurs .

(a) Explain the terms 'compression' and rarefactions of a wave. What type of waves consist of compressions and rarefactions? (b) A worker lives at a distance of 1.32 km from the factory. If the speed of sound in air be 330m//s , how much time will the sound of factory siren take to reach the worker?

Answer the following. What is compression and rarefaction?

Draw a longitudinal wave and mark its compressions and rarefactions.

One compression and one rarefaction makes two waves.

Name the following One compression and one rarefaction

Assertion : Sound waves travel in the form of compressions and rarefactions in air. Reason : Because crests and troughs cannot be sustained in air, therefore, sound waves cannot travel through air in the form of transverse waves.
