In the late 18 th century, German physicist and musician Ernst Chladni demonstrated how vibrations could be used to create striking imagery. By spreading fine sand across the top of a metal plate and ...
The origin of the idea of moving objects by acoustic vibration can be traced back to 1787, when Ernst Chladni reported the first detailed studies on the aggregation of sand onto nodal lines of a ...
Meet Steven Turner, curator at the Smithsonian's National Museum of American History, as he discusses the Smithsonian's scientific instrument collection. This video focuses on the plate developed by ...
Sounding off: theoretical force patterns for an underwater Chladni plate at two different frequencies. The force arrows illustrate why glass beads accumulate at the plate antinodes (shown in yellow ...
A metal plate, with salt sprinkled on top of it, is mounted on a mechanical oscillator that is powered by a function generator. At specific frequencies, the salt accumulates at certain locations of ...
Chances are you’ve seen the gorgeous patterns that sound waves produce when sand is sprinkled on a vibrating metal plate. Now French physicists have produced inverse versions of these patterns using ...
