Chladni Figures
How can the sand grain arrangement pattern deform? The thin plate vibrates in a complex manner, with some parts (nodal lines) remaining stationary, thus retaining the sand shaken from nearby vibrating areas, so a unique sand pattern appears on the thin plate. This is actually the Chladni pattern, also known as "Chladni sound pattern". In the 19th century, German physicist Ernst Chladni conducted an experiment by placing a wide metal plate on a violin and evenly sprinkling sand on it. Then he began to play the violin with a bow, and as a result, the fine sand automatically arranged into different beautiful patterns, and as the tune played by the strings varied and the frequency continuously increased, the patterns kept changing and becoming more complex—this is the famous Chladni pattern.
