There is a shiny, sand-covered platform in the system. As the signal generator works, the plate is made to vibrate at certain frequency, constructive interference move fast up and down, same points do not move at all because of destructive interference. If we scatter a handful of sand over the plate the sand is going to rush towards the points that do not move from the moving points. This way, the designs that are formed by the non-moving point become visible. These designs are called "Chladni Designs".

Since the vibrating plate has more than one resonance frequency, if we vibrate the plate at a rising frequency, as it reaches to normal resonance frequencies, different Chladni designs would be formed.
