Can ultrasound be refracted
WebAnother important case in which sound waves bend or spread out is called refraction. This phenomenon involves the bending of a sound wave owing to changes in the wave’s … WebRefraction of Sound. Refraction is the bending of waves when they enter a medium where their speed is different. Refraction is not so important a phenomenon with sound as it is with light where it is responsible for image formation by lenses, the eye, cameras, etc.But bending of sound waves does occur and is an interesting phenomena in sound. These …
