To observe the reflection of sound, take a drawing board and fix it on the floor. Put two metallic or cardboard tubes as shown in Fig. These tubes are making some angle with each other.The reflected sound waves enter the second tube and are heard by the ear placed in front of the second tube.

Explanation:

Sound:- When sound travels in a given medium, it strikes the surface of another medium and bounces back in some other direction, this phenomenon is called the reflection of sound. The waves are called the incident and reflected sound waves.

It is a form of energy produced by vibration and it needs medium to propagate. Reflection of sound: As light reflects when it strikes any hard object (opaque), sound also gets reflected when it strikes any object. The angle of incidence is always equal to the angle of reflection.

The sound you hear ringing in an auditorium after the band has stopped playing is caused by reflection off the walls and other objects. A sound wave will continue to bounce around a room, or reverberate, until it has lost all its energy. A wave has some of its energy absorbed by the objects it hits.
