Through illustrated diagrams and animations, students explore the broken pencil phenomenon and light refraction.

Illustrated diagrams in this tutorial help students understand the properties and functions of lenses.

In this lesson, students learn that light travels in a straight line from a light source and that ray diagrams help us understand how an image will be created by a lens. In the accompanying activity, students explore the concepts behind...

Site provides a diagram as well as a scientific explanation of light reflection. Includes links to ray optics, light and physics.

Georgia State University provides a discussion of curved mirrors and ray diagrams. Shows and explains the process of drawing a ray diagram to determine the image location, size and orientation.

A reference page that explores how an image is formed in a concave mirror. Page includes a ray diagram that shows the geometrical lines of sight.

This resource provides a good description of the cathode ray tube, with a very clear diagram and links to more in-depth information.

This physics department site features an indexing page for a variety of pages pertaining to atmospheric optics. Topics include rainbows, halos, auroras, mirages, star twinkling, sunsets, green flashes, coronas, and more. Excellent...

From the Atomic Archive - the online companion to the award-winning CD-ROM. This page (and the couple that follow from it) describe the use of fusion reactions in a hydrogen bomb. A schematic diagram of an H-bomb is given and discussed....

Students discover how mirrors affect optics in this module through reading informational text, watching animations, and answering self-checking practice questions.

A discussion of how to make a refraction exhibit using a Fresnel lens. Consists of assembly instructions and a "To do and notice" section.

Light travels as waves. Waves can be described by their amplitude, wavelength and frequency. The speed of a wave can be calculated from its frequency and wavelength.

A discussion of Christian Huygens' contribution to wave optics, and particularly to our understanding of the reflection and refraction of light. Excellent diagrams and a geometric proof on why the law of reflection is mathematically...

Using the diagram provided, calculate where a ray of light coming through a pinhole hits an image plane.

This page is a continuation of a tutorial about light reflection and refraction. It contains a diagram and suggestions on how to derive Snell's Law, which governs the refraction of light in a medium. For background to this derivation,...

This calculus tutorial with curved mirrors includes narrative and video presentations as well as other interactive tools.

In this activity, students construct their own pinhole camera to observe the behavior of light.

In this activity students will create images of images of images that can repeat forever. Students will recreate this effect by setting up two acrylic plastic mirrors.

Diagrams and discussion of the "collection of 1-dimensional records" that make up a CAT scan.

A discussion of how to make a magnifying lens exhibit using a water-filled flask and a light bulb. Consists of assembly instructions and a "To do and notice" section. Great for a teacher demonstration or a student project.

This is an extremely in depth look at the various different joints and their range of motion. Labeled diagrams are provided for each type. Illustrated quizes and x-rays can be accessed for each joint classification.

Dozens of statistical terms are defined and illustrated in this glossary.
