What is the law of reflection of wave?
Reflection is the changes in direction of a wave front at an interface between two different media so that the wave front returns into the medium from which it originated. Common examples are including the reflection of light, sound and water waves. The law of reflection says that for specular reflection of the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection. In acoustics, reflection causes echoes and is used in sonar. In geology, it is important in the study of seismic waves. Reflection is a observed with surface waves in bodies of water. Reflection is a observed with many types of electromagnetic wave, besides visible light. Reflection of VHF and the higher frequencies is important for radio transmission and for radar. Even hard X-rays and gamma rays can be reflected at the shallow angles with special “grazing” mirrors. Laws of Reflection of Sound: 1.The reflection of the sound follows the law “angle of
