Our Resonance Apparatus is compact for easy storage and more durable than glass models. Fill with water and raise and lower the inner tube instead of using a reservoir to control the length of the air column.

We recommend the use of a signal generator such as a LabQuest 3* or the Frequency Generator with the included mini speaker and a sensor such as the Go Direct Sound. Basic use instructions are included.

To relate the speed of sound to temperature, you will need a thermometer or temperature probe.

* Can also be used with the original LabQuest or LabQuest 2
