Your whole class will be able to
clearly see your demonstrations of
propagation, reflection, diffraction,
frequency-wavelength-velocity
relationships, and interference and
phase differences when you place the
ripple tank on your overhead projector.
It comes with a clear plastic ripple
tank, wave generator, and a variety of
barriers. The apparatus attaches easily
to a ring stand, available separately.
The wave generator requires a variable
low voltage DC power supply, or a 1.5
V dry cell with rheostat, also available
separately. Size: 13”L x 12”W.
