Beats

Simulation of Beats

This simulate the beats produced when two wave of similar frequencies are superimposed.

Set the amplitudes of the two component waves using the A₁ and A₂ sliders.
To see the two component waves check the Show components checkbox
The blue wave has a set frequency. Use the frequency (f) slider to set the frequency of the second purple wave.
Check Show resultant to display the superposition when the displacements of the two waves are added,
