Bow or drive a metal plate at a resonant frequency and sand sprinkled on top dances away from the moving areas and settles along the still nodal lines — Chladni figures. Each pair of mode numbers gives a different symmetric pattern, a direct, physical picture of a two-dimensional standing wave.

Governing equation

cos \frac{2 π x}{L} cos \frac{3 π y}{L} - cos \frac{3 π x}{L} cos \frac{2 π y}{L} = 0

Reading this result: Modes (2, 3) sum to an odd number, breaking the diagonal symmetry so the sand figure differs across the two diagonals.
