Sound wave also gets reflected as light waves do. Bouncing back of sound wave from the surface of solid or liquid is called reflection of sound.
Reflection of sound follows the Laws of Reflection as lightwave does. This means the angle of the incident wave and reflected wave to the normal are equal.
For reflection of sound, a polished or rough and big obstacle is necessary.
Reflection of sound is used in many devices. For example; megaphone, loudspeaker, bulb horn, stethoscope, hearing aid, soundboard, etc.
