laws of reflection of sound
Introduction to Laws of Reflection of Sound:
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 incidence equals angle of reflection", sometimes called the law of reflection.
2.The incident , the reflected and the 'normal' wave all lie in the same plane
3.When a longitudinal sounds wave strikes a flat surface, sound is reflected in a coherent manner provided that the dimension of the reflective surface is large compared to the wavelength of the sound.

Sound reflection
When a longitudinal sounds wave strikes a flat surface, sound is reflected in a coherent manner provided that the dimension of the reflective surface is large compared to the wavelength of the sound. Note that audible sounds has a very wide frequency range (from 20 to about 17000 Hz), and thus a very wide range of wavelengths (from about 20 mm to 17 m). As results, the overall nature of the reflection varies according to the texture and structure of the surface. For example, porous material will absorb some energy, and rough materials (where rough is relative to the wavelength) tend to reflect in many directions—to scatter the energy, rather than to reflect it coherently. This leads into the field of architectural acoustics, because of the nature of these reflections is critical to the auditory feel of a space. In the theory of exterior noise mitigations, reflective surface size mildly detracts from the concept of a noise barrier by reflecting some of the sound into the opposite direction.
