How Do a Plate, Violin Bow, and Sand Enable Us to See Sound?

When a Chladni plate is covered with sand and struck with a violin bow, distinct standing wave patterns form at different resonant frequencies. How does that happen? Find out in this video, where we try forming patterns on a Chladni plate and demonstrate the physics behind the phenomenon with a simulation app. After watching the video, learn more about Chladni plates on the COMSOL Blog:
