Straight wave reflection from straight barriers, 80-231, approx 3 minutes Single straight pulses are reflected from a straight barrier placed parallel to the wave front, then at 35, 45 and 55 degrees.

The equation needed when studying waves is: wave speed = frequency x ... so they can be observed. and some ripple tanks also have a signal generator, to control what frequency you're setting ...

A ripple tank can be used to measure and calculate frequency, wavelength and the speed of waves on the water's surface. A ripple tank is a transparent shallow tray of water with a light shining ...
