PURPOSE: Fourier – Making Waves: Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelength and period. See how changing the amplitudes of different harmonics changes the waves. Compare different mathematical expressions for your waves.

DESCRIPTION: Start the simulation from the demo computer. It is posible to download the PhET simulations onto your laptop. See the demo group for assistance.

SUGGESTIONS: Practice before you use this simulation in class.

EQUIPMENT: Demo computer and a projector

SETUP TIME: 15 minutes
