Chladni Figures
★Exhibit Content: Chladni figures, sound propagation and vibration ★Interaction: Electromechanical interaction ★Operation: 1. Press the "Sand Feed" button, and the automatic mechanism places sand onto the plate; 2. Press the "Start" button, adjust the knob to select a frequency, and see what patterns can be drawn. ★Exhibit Description: The exhibit consists of a base, metal plate, sand, speaker, knob, sand feeding mechanism, and digital display. Through electromechanical interaction, it demonstrates the phenomenon of Chladni sound patterns. Visitors operate the sand feeding mechanism to place sand on the metal plate, start the speaker, and adjust the knob to select different frequencies. The patterns formed by the sand on the vibrating plate will vary accordingly. ★Scientific Principle: When sand falls on the metal plate and the speaker is turned on, the sound waves emitted by the speaker cause the metal plate to vibrate. These vibrations propagate along the metal plate and reflect when encountering boundaries, superimposing with incident waves to form standing waves. The characteristic of standing waves is that certain points on the waveform remain stationary (nodes), while points between adjacent nodes vibrate up and down (antinodes). Under vibration, the sand gathers at the nodes, forming unique patterns known as Chladni figures. By adjusting the knob to select different frequencies, the vibration mode of the metal plate changes, which in turn alters the arrangement of the sand, presenting various patterns such as squares, circles, triangles, hexagons, etc. In addition, visitors can actively produce sounds, such as shouting, to make the metal plate vibrate at different frequencies, generating even more diverse patterns.
