WebPropagation of Sound Waves Class 9 - Concise Physics Selina Solutions Exercise 8 (A) Question 1 What causes sound? Answer Sound is produced when a body vibrates. … WebWhen a sound wave is incident on a solid or liquid surface, it bounces back onto the same medium. This is known as the reflection of sound. Like light, sound too undergoes reflection from any hard surface and obeys the same laws of reflection, which light obeys. WebAug 9, 2015 · A wave is a disturbance which moves through a medium by the vibration of the particles of the medium. So sound is considered as a wave. Since sound waves are produced due to the vibration of particles of the medium sound waves are called mechanical waves. 4.
