WebFermat famously stated in the 1630’s that a ray of light going from point A to point B always takes the route of least time -- OK, it's trivially trivially true in a single medium, light rays … WebMar 30, 2024 · Fermat's Principle states that light travels along the path of least time. From basic mechanics, the time for a particle to travel from a point A to a point B is t a → b = ∫ a b d s v. Here d s is an arc length and v is the velocity of particle. In general, the speed of the particle has a dependence on the path taken.

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 is the principle of least time, which is one of the principles which connect ray optics and wave optics.

"WebThe ﬁrst way of thinking that made the law about the behavior of light evident was discovered by Fermat in about 1650, and it is called the principle of least time, or Fermat’s principle. His idea is this: that out of all possible paths that it might take to get from one point to another, light takes the path which requires the shortest time. " - Fermat light principle
