Question
What are mechanical waves? Give examples.
Solution
The waves which require a material medium for their propagation are called mechanical waves. The propagation of mechanical waves depend upon the elastic propertie so the medium. Hence, they are also called elastic waves.
Examples of mechanical waves :
(i) Sound waves in air.
(ii) Waves over water surface.
(iii) Waves produced during earthquake also, known as seismic waves.
