WHAT IS MULTIPLE REFLECTION OF SOUND?
Ans : Multiple reflection of sound is the process in which sound waves bounces off obstacles and reflects many times before reaching the destination.
 Sound is constantly being reflected off many different surfaces when the reflected sound is heard separately, it is called an echo.
Sound is reflected from a surface at the same angle at which it strikes the surface. This fact makes it possible to focus sound by means of curved reflecting surfaces in the same way that curved mirrors can be used to focus light.Multiple reflection of sound waves is also used to focus sound in a megaphone.
