30 OPTI 201R 2.2 Fermat's Principle "In its simplest form, Fermat's principle states that light rays of a given frequency traverse the path between two given points in the least amount of time." (pg.31) ! A ray represents the shortest time between two points. ! Fermat's principle actually defines a ray of light. Fermat's principle: " can be derived from quantum mechanics. " leads to the "basic law of optics": in a homogeneous medium, Light Travels in Straight Lines . " leads to the Law of Reflection. ! describes the reflection from plane mirrors. ! describes the reflection from curved mirrors. ! describes the process of total internal reflection. " leads to the Law of Refraction (Snell's Law). ! describes the process of the bending of light (refraction) as it passes through different media. ! describes the process of the bending of light (refraction) as it passes through a lens (lenses). ……. .is the foundation for all of geometrical optics!!!!!
