[Free Registration/Login Required] In the scenario shown here, the laser cannot shine through the black barrier but can hit all three targets by reflecting off of the floor. Use the red dot to change the angle of the laser generator and...

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.

The meaning and cause of refraction--as well as Snell's law of refraction--are discussed. Includes an interactive problem-solving form in which visitors relate angles of refraction to the incident angle and the indices of refraction.

Illustrated examples and interactive practice problems that introduce students to the concept of the critical angle, the angle of incidence that provides an angle of refraction of 90-degrees.

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.

Use the angle of incidence and the angle of refraction to determine the index of refraction for a material.

This task asks learners to use similarity to solve a pool table problem. Students must use the fact from physics that when an object bounces off of a wall, the angle of incidence equals the angle of reflection. Aligns with G-SRT.B.5.

Students can see light reflected and refracted in this demonstration. They will also discover the total internal reflection of light.

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...

The law of reflection is discussed and explained, accompanied by an animation depicting this law. Includes a list of links to detailed information about certain types of reflections.

An interesting and engaging activity where students work in groups with a laser pointer and small mirrors. They must use their knowledge of angles of reflection to bounce the laser beam from mirror to mirror until it hits a target at the...

Through an illustrated tutorial and some interactive practice problems, students learn about the law of reflection of light.

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

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.

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.

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,...

Contains a four step procedure to deriving the law of reflection using algebra, Fermat's principle, and calculus (simple derivatives). This is good for an in-class theoretical exercise.
