This page is a free multimedia tutorial on lenses, appropriate for high school students in an introductory physics course.  Materials are formatted in Adobe Flash, with short video clips, animations, and interactive question-and-answer sets.  In this segment, students interactively explore how optical images are created by refraction through lenses.  Included are multiple diagrams of convergent and divergent lenses, plus problems encountered by technicians in the field of optics.  This resource is part of a full module on the physics of optics published by the NROC.

Please note that this resource requires Flash.
Editor's Note: These materials could be very useful for students with certain learning disabilities.  The modules are designed to spark student interest through visual appeal and are accompanied by voice narration.

This resource is part of a Physics Front Topical Unit.

Topic: Nature and Behavior of Light
Unit Title: Microscopy and Optical Devices

How does a simple lens work?  This interactive, voice-narrated tutorial gives beginning students an introduction to both concave and convex lenses.  It provides detailed diagrams of how they refract light, converging or diverging the beam depending upon the shape of the lens.  Included are self-guided question-and-answer sets.
