Chladni figures

Chladni figures are patterns created on a vibrating surface when sand or other fine particles are sprinkled on it. As the surface vibrates at different frequencies, the particles move and gather in specific areas, forming symmetrical designs. Named after the 18th-century physicist Ernst Chladni, these figures visually demonstrate the principles of vibrational modes and sound waves. Each pattern corresponds to a distinct frequency, illustrating how sound energy travels through materials. Chladni figures are used in physics and engineering to study acoustics and the behavior of vibrating systems.
