In this illustrated physics tutorial, students investigate several of the types of problems that you will have to solve, and learn the task of tracing the refracted ray if given the incident ray and the indices of refraction.

Complementary and Supplementary angles are explored in this tutorial video. [9:17] A PowerPoint presentation provides definitions of angle terms and a video offers examples for finding the missing angle in a supplementary or...

Find a quick, concise explanation of angles and types of angles. Several examples are given to help you understand how angles are formed and the different types of angles.

In this lesson plan, students learn about four types of angles: adjacent, vertical, supplementary, and complementary. They explore the relationships between these types of angles by folding paper, measuring angles with a protractor, and...

Through illustrated examples and interactive practice problems, students explore the details of Snell's Law.

Get independent practice identifying points, lines, rays, planes and angles. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.

Recognize rays, lines, and line segments in geometric figures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login Required] Students explore identification of angles by vertex and ray by navigating through the interactive learning module and then answering questions that go along with the module. Students can also learn more...

Provides details about the properties of straight lines, types of straight lines, line segments, rays, curved lines, and types of angles.

Students can review basic geometric terms using these self-check, multiple choice questions. Three levels of questions are provided.

Defines the refraction of light and provides an applet for investigating it.

A list of geometry definitions and a matching activity.

In this Cyberchase video segment, Harry tries to snowboard and learns how to measure and identify many common angles.

[Free Registration/Login may be required to access all resource tools.] In this module, discover and solve problems involving the index of refraction, and investigate problems involving Snell's Law.

The CyberSquad has to deal with angles and distances to locate a treasure chest in this video segment from Cyberchase.

In this lesson, students use line segments, angles, and parallel and perpendicular lines in order to create a one point perspective drawing.

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.

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...

This site from Georgia State University is an indexing page for several other pages on the topic of reflection. Topics are treated in an understandable manner and utilize meaningful graphics.

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,...

Provides examples and a video lesson that introduce fundamental statements of geometry.

Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual...

This physics department site explains how prisms work and their purpose in the dispersion of light. Explains the angle of deviation and includes an interactive form in which visitors calculate the angle of deviation and receive immediate...

Students find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, student teams design and build their own spectrographs, researching and designing a...
