WAVES

As sound waves move through water and salt, they vibrate in geometric patterns that visualize the nature of waveforms.

Series: PHENOMENA, Episode 3: WAVES, Runtime: 06:33

Synopsis:

Waves are all around us. Their influence is visualised by channeling soundwaves through liquid and solid particles. In this experiment, water rests in an upright facing speaker, and salt rests on a high frequency mechanical wave driver. The instruments are activated, sound waves move through the water and salt causing them to vibrate in resonance with the waveform, revealing geometric patterns. The patterns change with the pitch and volume of the sound wave, visualizing the incredible geometric nature of waveforms.

The ‘Cymatics’ experiment was the first film of the series, created by Josef and his dad Mark. The ‘Chladni plate’ experiment was filmed with the assistance of RMIT University, Melbourne. These films were screened at Adelaide Film Festival (2018), Splendour In the Grass (2019) and SCINEMA International Film Festival (2020).
