DESCRIPTION
Sprinkle sand on the
plate. When the function generator is tuned to a
resonant frequency of the plate, sand will collect in the
nodal lines. Tune to different harmonics to show
different patterns of standing waves.
NOTES
We have a round and a square
plate supported at the center and an oval plate supported at
one focus.
You can create your own node by
touching the edge of the plate.
