Amazing Resonance Experiment (video)

Amazing Resonance Experiment

Science could be also interesting…

See the video with this experiment in which are used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker.

The experimenter first adds sand to the plate then begins playing a tone. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration.

The sand “falls” into those areas, creating beautiful geometric patterns. As the frequency increases in pitch the patterns become more complex.
