Chladni Plates
Chladni Plates
- Description
- Ernst Chladni (1756-1827) was a German musician who studied the physics of sound. The Chladni Plate, one of his key inventions, was a flat piece of metal covered with a fine layer of sand; when a bow was drawn along one edge of the plate, the sand arranged itself in such a way that the nodal patterns became apparent.
- This example consists of two circular brass plates held in an iron clamp. The Smithsonian Institution bought it in the 1860s, probably from Rudolph Koenig Paris.
