Sound reflects from a smooth surface the same way light does---the angle of incidence is equal to the angle of reflection.
Its on page 385.
Reflection is the return of sound waves from surfaces on which they are incident.
The reflection is vibration because sound is equal to vibration
Sound can be reflected off things - a reflection of sound is called an "echo" and can be heard.
Quick Answer:The angle of incidence is not equal to the angle of refraction.The angle of incidence is equal to the angle of reflection.Better Answer:(This answer applies to all waves, e.g. sound, ripples, earthquakes, but the answer is given in terms of light waves.)The angle of incidence never equals the angle of refraction except in the peculiar circumstance when there is an interface between two materials of exactly the same index of refraction.The angle of refraction is the direction of the wave exiting the surface and the angle of incidence is the angle entering the surface.These two angles are related by Snell's law and by Snell's law one would conclude that the index of the medium of the incident beam would be exactly the same as the index of the transmitted beam. In optical terms, it would mean the wave propagates as though there were no interface and the two mediums were actually the same medium. In that case, there would be no reflection as well.So, one does not expect this to happen, not because it can't, but because the wave travels through the surface as though the surface did not exist and that is both unusual and uninteresting.
This is called reflection of sound. It's like a sound wave bouncing on a trampoline.
Angle of Incidence is equal to Angle of Reflection.
For refraction, the general relationship is given by Snell's Law.

a reflection
The reflection is vibration because sound is equal to vibration
refraction is where the soubd waves bend, reflection is when sound waves bounce off of things and change direction.
