Cymatics: Turning Sound into Art

The video explores the concept of sound as vibrations through a medium, explaining how sound waves can affect their surroundings. It introduces cymatics, a method to visualize sound waves using sand on a plate, and explains the principles of longitudinal waves and standing waves. The video also discusses interference patterns, nodes, and how different frequencies create various patterns. Finally, it highlights a 3D cymatics experiment where researchers used ultrasound waves to levitate objects, demonstrating the potential for creating floating art.

What is the difference between constructive and destructive interference in sound waves? Provide examples.

How did researchers at the University of Tokyo use sound waves to create floating art?
