Chladni's law

Chladni's law refers to a principle in acoustics, particularly in the study of vibrations and wave phenomena. Named after the German physicist Ernst Chladni, who is often regarded as the father of acoustics, it pertains to the patterns formed by vibrating surfaces, which are often visualized using sand or other fine materials. When a plate or membrane is vibrated at specific frequencies, it demonstrates nodal lines (points of no vibration) that separate regions of maximum movement.
