3B50.20 - Ripple Tank

Code Number:
3B50.20
Demo Title:
Ripple Tank
Condition:
Good
Principle:
Wave Phenomenon
Area of Study:
Acoustics
Equipment:
PASCO and Older Round Ripple Tanks with Accessories, Power Supply (0 to 6 VDC), Food Coloring (if desired), Water, and 4 Video Tapes (Ripple Tank Demonstrations).
Procedure:

The PASCO ripple tank unit is easy to use and displays well in class.  Note that there are included accessories for measurement, barriers, and wave source attachements.  About 1 liter of water seems to work well.

We never use the large round ripple tank in class because the videos are not only more visible but also faster and more accurately done.  This ripple tank is good for small groups if you add the strobe from the Pasco unit.
