This activity demonstrates how white light, such as that from an overhead projector, is broken up into its component colors by a diffraction grating. Students will learn the relationships between light's wavelength,...

This activity from the Exploratorium provides an introduction to the diffraction of light which indicates its wavelike properties. Two pencils are used to create a slit through which a flashlight bulb or candle’s light...

In this video from the ICT Center, learn about interference and diffraction. See how the wave properties of light are used to explain interference patterns on a screen, and learn about related technologies such as the...
