Refraction and the Ray Model of Light tutorial

This comprehensive tutorial focuses on refraction as it applies to Snell's Law, total internal reflection and lenses.  "Refraction at a Boundary," "The Mathematics of Refraction," "Total Internal Reflection," "Interesting Refraction Phenomena," "Image Formation by Lenses," and "The Eye." Each tutorial page includes illustrations and questions to check understanding. Student extras and a teacher's guide for each page provide links for further investigation. The law of refraction is defined and explained in terms of changes in the speed of light across different mediums. Refraction is then used to explain phenomena such as total internal reflection, dispersion, and lenses. Ray diagrams are constructed for converging and diverging lenses, which are then used to model the human eye and vision correction.
