My students have been working on a series of four experiments that are part of a major lab "Wave-O-Rama" that is trying to weave a common thread amongst all of them; what happens to waves when they interfere or diffract?

One of the experiments, Nothing Beats Fourier, introduces students to the concept of synthesis of waveforms from basic sine functions through the use of WolftamAlpha and the iDevice apps that are listed below according to the level of Coolism.

Coolism: Fourier Synthesizer
Cool: Sound Uncovered
Semi Cool: Fourier Touch

Give these apps a try in your classroom and share how your experience went. In addition, if you wish to have a copy of my lab sheet, please fire me an email.
