In this physics tutorial, focus on the refraction of light in great detail. Explore the conceptual and mathematical principles governing the bending of waves as they cross the boundary between two media.

Site studies light refraction and provides illustrations several illustration. Contains links to Snell's Law, lenses, ray optics, light and much more.

This article from Khan Academy provides information about refraction and light bending. This information is intended for the Class 12 Physics Course (India).

Focusing on the question, "By how much does light refract when it crosses a boundary?" this physics tutorial will allow students the opportunity to explore these concepts of refraction.

In this illustrated tutorial, students will see a specific method for constructing ray diagrams for double concave lenses.

In order to understand refraction, students will explore the factors that affect the speed at which a light wave is transported through a medium.

Through illustrated examples and animated tutorials, students discover what causes refraction.

Investigate the behavior of a water filled vial, and discover why it acts like a magnifier. Includes full list of materials, procedures, and scientific explanation of what causes light rays to change direction.

An interactive Java applet which allows the user to investigate the path of light through a lens shape object. The shape of the object, the index of refraction of the material, and the location of the incident rays can be altered.

Students learn how the Archer fish can reach out of the water and catch its prey with pinpoint accuracy, despite the physics that causes refraction of light.

In this interactive physics tutorial, students will learn about a mathematical equation relating these two angles and the indices of refraction of the two materials on each side of the boundary.

Through illustrated examples, students explore the physics phenomenon of total internal reflection when light travels through several medium boundaries.

An illustrated tutorial which takes students step-by-step through the process of drawing ray diagrams.

A tutorial which introduces students to the dispersion of light in more detail, and investigates the reasons why different frequencies of light bend or refract different amounts when passing through the prism.
