Chladni Plate Kit — Resonance & Standing Wave Demonstrator

Sprinkle sand on a metal plate. Draw a bow across the edge. Watch physics write its own geometry.

Chladni figures are among the most visually striking phenomena in all of physics. When a metal plate is driven at a resonant frequency, standing waves form — and sand migrates to the nodal lines where the plate doesn't vibrate, tracing out intricate, symmetric patterns. Each frequency produces a completely different pattern.

What you can demonstrate:

• Standing waves and resonance modes
• Nodal lines and antinodes
• Wave superposition and interference
• Eigenvalue problems in 2D (the mathematics of Chladni figures inspired quantum mechanics)
• Cymatics — the visualization of sound

Includes: Steel Chladni plate (25×25cm) · Mounting rod and base · Rosined violin bow · Fine sand · Instruction guide with frequency reference patterns

Used by Chladni himself to demonstrate wave physics to Napoleon. Now on your desk.
