Sound Visualised — Chladni Figure on Steel Plate
449.00 د.إ
A Chladni figure on a vibrating steel plate — fine sand self-organising into the standing wave nodal lines of a specific resonant frequency, the geometric pattern corresponding to the plate’s vibrational mode shape.
Description
Chladni figures are the visible manifestation of sound — fine sand or salt placed on a vibrating plate migrates to the nodal lines where the plate’s surface is stationary, forming geometric patterns that are direct maps of the plate’s standing wave mode shapes. This image was made by securing a square steel plate and driving it at a specific resonant frequency with a function generator and speaker, fine white sand spread on the plate’s surface and photographed from above as it settles into the nodal pattern. The frequency shown produces a 4th-order mode with six nodal lines in each direction, creating a grid-like pattern with nodal intersections at 36 points across the plate surface. Shot overhead at f/11 with a softbox above, the plate surface is uniformly lit, the sand pattern rendered with maximum contrast against the steel. The geometric regularity of the pattern — determined entirely by the plate’s dimensions and material properties — is a direct physical computation of the wave equation.
