WebFrom Fermat’s principle, one can derive the law of refraction. Law of Refraction Let light ray PQ, starting from point P and traveling through Q reaches to a stationary point R. Light ray PQ being incident on MM’, the plane of separation between the media a and b, at an angle ‘i’ and is refracted in the medium at an angle ‘r’ [Figure]. Web2.1 Derivation of Generalized Snell’s Law Based on Fermat’s Principle According to this principle, the optical path from point A to point B in the medium can be expressed as R B A nðrÞdr, nðrÞ is the refractive index of the medium.

Web(b) With the aid of a diagram use Fermat's principle to derive Snell's Law (c) A laser beam located beneath the surface of a liquid (which is open to the air above) is directed such that the beam makes an angle of 6 with respect to the surface normal. Webwe’ll discuss shortly.) Applying this principle, we can derive Snell’s Law. We can also use Fermat’s principle to derive Snell’s Law of Reflection, which states that the reflected ray makes the same angle with the interface as the incident ray. 3.3.2 Explaining Fermat’s Principle Now let’s explain Fermat’s Principle.
