The following two laws of reflection are applicable to sound waves as well. 

(i) The incident wave, the normal to the reflecting surface and the reflected wave at the point of incidence lie in the same plane. 

(ii) The angle of incidence ∠i is equal to the angle of reflection ∠r. 

These laws can be observed from figure

In the above Figure, the sound waves that travel towards the reflecting surface are called the incident waves. The sound waves bouncing back from the reflecting surface are called reflected waves. For all practical purposes, the point of incidence and the point of reflection is the same point on the reflecting surface. 

A perpendicular line drawn at the point of incidence is called the normal. The angle which the incident sound wave makes with the normal is called the angle of incidence, ‘i’. The angle which the reflected wave makes with the normal is called the angle of reflection, ‘r’.
