WebBy your reasoning light therefore ought to pass through the wall. This is clearly false. A wave e.g. ultrasound may reflect in part or totally from a surface/interface. The … WebAt incident angles higher than that which would create a 90 degree refracted longitudinal wave, the refracted wave exists entirely in shear mode. A still higher incident angle will result in a situation where the … 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.
