Superposition of Waves

Here's an animation showing how two waves of the same kind superpose (or interfere with each other, or add together) when they pass through each other.

There is also a javascript version of this animation, so you can run it direct from a browser. Check out the 'Superposition of Waves' page!

String Harmonics

Here's an animation showing how a string vibrates when it is plucked. It shows the first ten harmonics of the vibration, and the way that the string vibrates being due to just adding the harmonics together.
