Chladni plate

名词 n.

英文释义

名词 n.
  1. A flat sheet of metal (generally square or circular) mounted on a central pillar, over which sand or other particles are sprinkled, which when bowed vibrates and arranges the sand particles into patterns (Chladni figures), allowing for the visualization, and analysis, of sound.
    — […] the phenomenon of forced, or sympathetic, vibrations may be beautifully shown by having two Chladni plates exactly alike, and setting one in vibration by bowing. The sand will gather along the nodal lines, showing that vibrations of a certain character exists upon the plate. If, now, sand is scattered upon the second plate, and this is held near the first, the second will be thrown into vibrations similar to the first, […] as will be shown by the sand pattern upon the second appearing identical with that on the first.
