The sound can not only be heard, but also seen. They affect the air environment, we deflect its pressure from the equilibrium value, thereby creating sound waves that begin to propagate from the sound source, eventually reaching the listener. But sound waves can also be perceived visually. The vibrations they create affect small particles, causing them to form the most unexpected patterns.
The science that deals with the study of visible sound and vibration is called cymatics. By acting on a thin layer of particles or liquids with sound waves, you can create a real masterpiece.
Musician Nigel Stanford, inspired by the physics of sound, together with his band decided to record a music video in which he showed several scientific experiments related to cymatics.
