Snell's law gives the relationship between angles of incidence and refraction for a wave impinging on a dielectric. The law follows from the boundary condition that a wave be continuous across a boundary, which requires that the phase of the wave be constant on any given plane, resulting in n1*sin(theta1)=n2*sin(theta2) where theta1 and theta2 are the angles from the normal of the incident and refracted waves, respectively. Snell's law may describe reflection by letting n1=n2.
