GeoGebra Animations for Physics Teachers: Beats and Interference

 

The following animation is ideal for physics teachers to explain the phenomenon of interference when beats are formed by the combination of  two waves which have slightly different frequencies.

You can see the individual waves as well as the resultant wave. Constructive and destructive interference are displayed clearly within the animation.

This is the live animation for practice:
