Sound Waves Visualized with a Chladni Plate and Colored Sand [Video]

By Jason Fitzpatrick on December 13th, 2012

This eye catching demonstration combines a Chladni Plate, four piles of colored sand, and a rubber mallet to great effect–watch as the plate vibrates pattern after pattern into the sand.

A Chladni Plate, named after physicist Ernst Chladni, is a steel plate that vibrates when rubbed with a rubber ball-style mallet. Different size balls create different frequencies and each frequency creates a different pattern in the sand placed atop the plate. Watch the video above to see how rubber balls, large and small, change the patterns.
