Explanation:
Abstract: Because the refracted sound field of a finite beam extremely depends on the size and on the frequency of the generating element, Snell's law is not applicable to calculate the refraction angle of a finite beam

Snell's Law of Refraction fail when light incidents on the surface of separation of the 2 media normally or through the normal. It is because when light incidents through the normal, the angle of incidence is equal to zero. Therefore the angle of Refraction is also zero.
