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.

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.
