Question

to determine the laws of reflection of sound i.e., the angle of incidence is equal to the angle of reflection ​

Answer 1

If a sound is not absorbed or transmitted when it strikes a surface, it is reflected. The law for reflection is the same as that of light, ie., the angle of incidence of a sound wave equals the angle of reflection, just as if it were produced by a 'mirror image' of the stimulus on the opposite side of the surface.

Answer 2

m

Explanation:

angle of incidence is equal to angle of reflection it's only whenever the laws of reflection not sound
