Snell's Law 1

Author:

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: http://poppersdreamland.blogspot.com/2012/02/snells-law-1.html
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!
