Question

State thelaw of reflection of sound

Answer 1

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.

Answer 2

Law of reflection of sound waves states that ‘The angle of incidence equals angle of reflection. The incident sound ray, reflected sound ray and perpendicular line from point of incidence on reflecting surface, all lie on the same plane, perpendicular to the reflecting surface’.

The Laws of Reflection of Sound Waves are also applicable to Laws of Reflection of Light Waves.
