See the Buying Guide for this item's required, recommended, and additional accessories.
The Resonance Air Column (WA-9606) emits a very loud sound when the plunger is moved to a node position. It works as well as a water column but without the mess. The secret is in the long molded piston head, which is very efficient in reflecting the sound waves. The plunger handle is made of flexible acetyl so it will not break.
How It Works
The Resonance Air Column has a polycarbonate tube so it will not break or chip like inferior acrylic. It includes eight plastic snap-on rings which can be sled along the tube to mark the nodes. Then a meter stick is used to read the positions of the rings. The plunger handle is make of flexible acetyl so it will not break.
The Mini Speaker is made to fit with the Resonance Air Column. It can be powered with a function generator or an 850 Universal Interface. It is also useful as a stand-alone speaker for doing interference demonstrations. Two of the essentially point sources can output the same frequency and the spatial interference pattern can be explored.
