Resonance Air Column


A Very loud resonance A Tough polycarbonate tube A Use with speaker or tuning fork


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 plunger handle is made of flexible acetyl so it will not break.


This column has a polycarbonate tube, so it will not break or chip. It includes eight plastic snap-on rings that can be slid along the tube to mark the nodes. A meter stick is used to read the positions of the rings.


The Resonance Air Column can be used as a closed tube or an open one. In the closed mode, tuning forks or speakers are suitable for sound sources. In the open mode, a speaker with a signal generator is required to vary the frequency until the tube sounds a resonance.
