WebThe Chladni Plates. Make or buy Chladni plates, square and/or round. The number of plates depends on how many groups of students will be using the plates simultaneously. I recommend that each plate is used by a group of 2 to 6 students. For example, you'll need 4 plates if you have 4 groups of 6 students (24 students total). WebTracing the family tree of plate theory to its roots, one travels back to the American Revolution time period and finds Euler performing free vibration analyses of plate problems (Euler, 1766). Chladni, a German physicist, performed experiments on horizontal plates to quantify their vibratory modes. He sprinkled sand on the plates,
