See our Resonance Apparatus in action! The Resonance Apparatus is used for the classic experiment of determining the speed of sound using the principle of resonance in a tube closed at one end. Fill the apparatus with water and use a tuning fork or the included speaker to produce sound. Listen for the resonance while moving the inner tube, or use a sound sensor to locate the resonance lengths.

We recommend the use of a signal generator, such as the Frequency Generator, with the Resonance Apparatus’s included mini speaker and a sensor such as Go Direct Sound. To relate the speed of sound to temperature, you will need a thermometer or temperature probe, such as Go Direct Temperature.
