Soap Film Oscillations
To demonstrate standing waves in a two-dimensional medium.
Rectangular and circular frames, soap solution and flat pan.
This requires a good deal of practice and patience.
A large rectangular form and a circular form are provided for producing soap films using a specially-formulated soap solution. Careful movement allows production of various standing waves.
