Snell's Law 1

Ryan Hirst
When light crosses from one medium to another of a different density, its speed and wavelength change. Where it strikes the new surface at an angle, the transmitted wave is refracted -- it changes direction. More information:
Drag L into the medium with a higher Index of Refraction to view reflected vector R. The angle at which light fails to transmit due to the difference in density is the critical angle. ______ This is an old worksheet! Improved versions: Refraction: Vector intersections: Light Properties (book) :
