Reflection of Sound
As we know all the waves get reflected when struck with a hard surface. Sound waves are no different they also get reflected striking a barrier.
Reflection of sound waves implies that sound waves after hitting a hard surface get reflected back in the same medium. The only necessary condition of the sound wave is that the surface through which sound has to get reflected must be bigger than the wavelength of the sound wave.
The concept of reflection of the sound wave is used in musical instruments, megaphones, etc.
Laws of Reflection of Sound
Similar to the Law of reflection of light, sound also follows the law of reflection of sound. The laws of reflection of sound are,
Law 1: The Incident wave, reflected wave and the normal to the reflecting surface at the point of incidence all lie in the same plane.
Law 2: Angle of Incidence of the wave is equal to the Angle of Reflection of the wave.

Reflection of Waves
Waves are the disturbance created in the surroundings which are used to transport energy from point A to point B without transfer of matter. We also see different types of waves in our surroundings, when we throw a stone in the quiet pond we observe a disturbance travelling in the pond water formed by the striking of the stone this disturbance is called the wave.
Waves are found in many forms such as,
- Sound Waves
- Light Waves
- Water Waves
- Radioactive Waves
- Ultraviolet Waves
- Mechanical Waves
Energy is transferred through waves. The reflection of waves is the bouncing back of the wave after striking a hard surface.
In this article, we will learn about the reflection of waves, the laws of reflection of waves, etc.
