Web#1d Fourth year students Derive Snell’s Law for refraction in a crystal at a planar interface. The Lagrangian in the case of an anisotropic optical medium is given by L(r(s),r˙(s)) = n(r(s),bs(s)) r˙(s) . Here the refractive index is modelled as a function of both position along the ray r(s) and the ray directionbs(s), which is a unit vector WebThis is known as Snell’s law. The same logic holds for reflected waves: R is the same and λ is the same (since n1=n2 for a reflection) therefore θ1= θ2. This is usual the law of reflection: the angle of reflection is equal to the angle of incidence. For a fast-to-slow interface (like air to water), the angle gets smaller (the refracted ...
