Question

State the laws of reflection of sound waves and it two applications

Answer 1

HEY MATE.....


The following two laws of reflection of light are applicable to sound waves as well: The incident wave, the normal to the reflecting surface and the reflected wave at the point of incidence lie in the same plane. The angle of incidence ∠i is equal to the angle of reflection ∠r.

HOPE THIS HELP YOU...

Answer 2

• Reflection of Sound. ... The two laws concerned with sound reflection are as follows:
• The incidence angle will always be equal to the reflection angle.
• the incident sound waves, the normal at incidence point and reflected wave, all rest in a common plane.
