Solution
Yes, sound also follows the same laws of reflection as light waves. The laws of reflection of sound are as follows:
- The incident sound wave, the reflected sound wave and the normal drawn at the point of incidence. All three are in the same plane.
- The normal drawn at the point of incidence of the reflecting surface and the angle between the direction of incidence and the direction of reflection of the sound are equal.
