In 1680, English scientist Robert Hooke conducted an experiment demonstrating the nodal patterns of vibrating glass plates. He ran a bow along the edge of a flour-covered glass plate, causing it to vibrate and form stationary points known as nodal lines, where the flour accumulated. These patterns visually represented the modes of vibration of the plate. This foundational work was later expanded upon by German physicist Ernst Chladni in 1787, who systematically studied these patterns, now known
