The law of reflection of sound waves states that the angle of incidence is always equal to the angle of reflection. But unlike reflection of light on a highly smooth surface, in the reflection of the sound wave, a part of the incident wave gets transmitted to the medium where it hits. Acoustic mirrors can reflect and focus sound waves under water, but typical mirrors require very complex configurations or geometries. Sallam et al. designed, simulated, and experimentally verified a flat acoustic mirror for underwater applications. two laws of refraction, The incident ray, the refracted ray, and the normal to the interface at the point of the incident all lie in the same plane. The ratio of the sine of the angle of incident and the sine of the angle of refraction is constant for given pair of media. Sound waves mostly reflect back from any water-air boundary, making it nearly impossible to hear underwater sounds from above. But now physicists have devised a structure that, when placed in contact with the surface, can enhance sound transmission up to 160 times, allowing 30% of the sound energy through.
