Question

Q) After doing an experiment to verify the law of reflection of sound ,the student plotted the graph between angle of incidence and angle of reflection. what type of graph will be obtained?​

Answer 1

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.
