प्रश्न
Does sound follow the same laws of reflection as light does? Explain.
उत्तर
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.
