WebFermat's principle tells that a light ray will follow a path from point A to point B so that the optical path length of this path is an extremum over neighboring paths. I wanted to use this principle to prove the law of reflection. WebFermat's principle states that a light ray refracted across different media will traverse the fastest path as the physics for Snell's law. A geometric proof of Fermat's principle will be demonstrated as an intuitive approach to learn high school geometry and physical optics. It will be proved explicitly by showing that all alternative paths need more traversal time to … how old was peter breck when he died

Snell

WebFermat's principle yields Snell's law. In Fermat's Principle the optical path length between points A and B can be calculated in either direction, A to B or B to A, the result is the same. This leads to the principle of geometrical reversibility. Principle of Ray Reversibility: Any actual ray of light in an optical WebTable 26–2 shows the angles in air and in water according to Snell’s law. Note the remarkable agreement with Ptolemy’s list.
