Additional Info

• ID Code: G4-21
• Purpose: Show two-dimensional standing waves in a metal plate
• Description:

  Sand is sprinkled onto a circular or square thin metal plate, which is then stroked along the edge using a violin bow. The sand moves to nodal lines of the standing wave pattern. Stroking at one point while holding your finger at another point to forces a node at that point, if desired, creating a variety of standing wave patterns.
