Beats

In this applet two waves of equal amplitude are interfering. You can control the centre or nominal frequency of the waves and also introduce a small frequency difference between them. When you have set these two controls, click on the centre panel and the computer will draw out the wave.

This would be better with a time domain, so you could see that a 3 Hz difference in the two tones creates 3 beats per second.

URL is no good.

Good display of the effects of interference and frequency differences and their
relevance to the real world (such as in tuning musical instruments). The
explanation is helpful, and
there are tips on what to watch while playing with the applet

Technical Remarks:

Needed to manually update changes to the frequencies of the waves, which is nice
in that it doesn't eat up memory like other applets.
