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.

A discussion of refraction and its application to sound waves. Using analogies, graphics and real-life applications, this page and those that accompany it explain why and when sound waves bend.

In this interactive physics tutorial about refraction, students investigate the topic of the direction of bending of a light wave.

Guitar masters like Jimi Hendrix are capable of bending the physics of waves to their wills, plucking melody from inspiration and vibration. But how do wood, metal, and plastic translate into rhythm, melody, and music? Oscar Fernando...

An experiment using Jell-O to create lenses, to see how light behaves with flat, concave, and convex lens surfaces. With an explanation of what is observed, and a link to an informative article on lenses.

Lesson plan should be used for intermediate learners. Students work in pairs or groups to create a shoe box that will bend light.

Fourth graders learn how light waves bend differently in different mediums.
