Direction of Bending Video Tutorial

The Direction of Bending Video Tutorial explains with great detail and numerous examples how to use information about the relative speed, optical density and index of refraction values of two materials in order to predict the direction that light will refract when passes across the boundary between the two materials. The video lesson answers the following question:

  1. How can one predict the direction that an incident ray refracts when it crosses a boundary?
