Then, also necessarily, each of the rays from P 1 to P 2 are the shortest path, and thus are all equal. Twitter. Facebook.

WebJan 20, 2024 · The first approach is by Fermat's principle of least time. The time taken for light to travel around a circular trajectory must not change for a small perturbation in it's path; from there, by equating the flight time for two circular trajectories, we would get 2 π R n 0 c = 2 π ( R + h) n ( h) c ⇒ n 0 R = n ( h) ( R + h) Web1.

WebJul 24, 2024 · Fermat's principle is actually a least-time principle. What it says is, that out of all possible trajectories between two points, light is going to follow the one that minimizes the time spent traversing that trajectory. WebFermat's principle says that light travels between two points along the path that requires least time as compared to other nearby paths. But why this is so? Why can't light follow other paths?
