Bending Light Backwards [mp3 Audio file] - Researchers made light bend through a prism in the opposite direction from normal light. The trick is a new kind of material with special properties. This material has the potential to be used to build near perfect lenses. Quirks & Quarks April 14 2001 Audio File Good STSE student research

Double slit interference. A simple wave generator showing double slit interference. The distance between slits and the wavelength can be changed. Animation stops when the left mouse is held down and a calculation is displayed for the position of the mouse pointer. Coloured lines show the waves involved in the calculation.

This site has now been moved to http://www.atoptics.co.uk/ Identified as a deadlink until it can be changed in the VL. Atmospheric Optics This site explains a host of visual spectacles - rainbows halos glories coronas and many more. Some can be seen almost every day or so some are once in a lifetime sights.

VISUALIZING THE ELECTROMAGNETIC SPECTRUM A nice introductory demonstration. It requires collecting a fair amount of equipment the first time.

A video camera can be quickly fitted with a diffraction grating and used as a spectroscope. The zoom lens provides a way to see detailed structure in spectra of gas elements and other sources of coloured light.

A large plastic diffraction grating can be easily attached to an overhead projector to project the visible spectrum of the lamp. Beakers with indicator dyes can be placed on the projector stage to show changes in the spectrum as the dyes change colour. Good for relating colour theory to absorption and transmission media. Also good for introducing the invisible parts of the EM spectrum (i.e.IR&UV)

Bubble, Bubble, Toil and Trouble Bubbles are intrinsically interesting objects that attract the attention of old and young alike. I offer here but a few descriptions of demonstrations and activities. There are a great many more available. You’ll find some suggested resources at the end of this article.

Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them.

Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern. Excellent illustration of diffraction and interference of different types of waves in 2 dimensions.
