The first step to Visualize Acoustics! At special frequencies, standing waves appear on the plate, driving the sand away from the points of large vibration to points of no vibrations. Unique patterns are formed at different resonance frequencies becoming increasingly complex and beautiful as the rate of oscillation increases.
