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.

[Free Registration/Login Required] This flipchart is an introduction lesson on light. It explains absorption, transmission, and reflection. It contains real pictures that allow students to see how matter in an object determines how much...

This resource offers a hands-on activity for science teachers to teach about the eye and it's ability to see images. Also discusses refraction and reflection. This resource is in PDF form; requires Adobe Reader.

[Free Registration/Login Required] This flipchart introduces fifth graders to the science of light. Principles such as transparent, translucent, opaque, reflection, and refraction are covered. Concave and convex mirrors and lenses are...

A four-lesson tutorial on the reflection and the ray model of light. These complete tutorials include informational text, interactive activities, animations, and quick, interactive comprehension questions.

[Free Registration/Login may be required to access all resource tools.] Students explain the ray model of light, describe the law of reflection, and investigate how images are formed from flat mirrors.

[Free Registration/Login may be required to access all resource tools.] Students learn about total internal reflection. More specifically, they will learn what the critical angle is, how it is derived and how to solve for it in real life...

A mini-activity, which uses LEGO MINDSTORMS NXT intelligent bricks and light sensors gives students a chance to investigate how light sensors function in preparation for the associated activity involving the light sensors and taskbots.

The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in...

Through diagrams and illustrations, students explore how images are formed through the physics law of reflection.

"How Do We Know Light Behaves as a Wave?" An answer is provided in this discussion of the polarization of light and the use of Polaroid filters in sunglasses. The four methods discussed on this page are: polarization by transmission,...

What happens when a ball is thrown against a wall? This narrative illustrates how light is reflected or refracted in different circumstances.

A series of incident rays and their corresponding reflected rays are depicted in the diagrams in this tutorial. Each ray strikes a surface with a different orientation; yet each ray reflects in accordance with the law of reflection.

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

This is a quiz covering reflected, refracted, shadow, and camera rays.

In this physics tutorial, students explore the phenomenon of the fact that without light, there would be no sight.

This is a 10-question exercise/quiz pertaining to reflection and refraction.

Punctate keratitis is an eye disease that results in abrasions on the epithelial cornea. One of the leading causes of the disease is the overuse of contact lenses. A research team is investigating the optical properties of four new types...

In this series of interactive physics tutorials, students will focus on the wavelike nature of light.

This high school resource shows how the blue of the skies and the red of the sunsets can be explained by the interaction of sunlight with atmospheric particles which causes scattering of light.

Students investigate an example of interference that provides further evidence in support of the wavelike behavior of light.

Through illustrated practice problems and video clips, students learn about polarization of light.

Questions for reflection for the painting For the Light by Susan Rothenberg. Includes image of the painting and an audio version of the questions. Includes links for more information about the painting and artist as well as a link to "My...
