You've probably noticed the colorful patterns "reflecting" from the shiny surface of a CD disk. What you are seeing is actually diffraction of white light, and the rainbows of color are diffraction patterns. In this project you'll learn...

In this activity, you will make a glass object disappear by eliminating the reflection from and the refraction by the glass object.

This lesson engages students in learning about light through multiple sources. Students will learn how light is produced, reflected, refracted, and separated. Students will communicate their findings through an independent project that...

Demonstrate for students how a round bowl of water can act as both a magnifier and a lens.

This experiment demonstrates the concept of total internal reflection, using basic materials. Accompanied by a detailed explanation of what's happening, and links to articles on reflection and refraction.

After constructing a frame with a mirror made of horizontal strips, explore what your face would look like if it was made up of half of someone else's.

The researchers in this study set up a mobile lab including six 3D cameras, three laptops, and 70 luminescent markers. Volunteer dancers were prepped with the markers before turning in front of the cameras, which flash infrared light to...
