Calculus of Variations
Fermat's Principle
Fermats principle is thatlight takes a path between two points that requires the least amount of time.
If we let S represent the path of light between two points then
light takes the time to travel between two points can be expressed as
- t = \int_A^B dt =\int_A^B dt =
