Speed of Sound in Air

The purpose of this activity is to measure the speed of sound in air using a tube that is closed at one end. Use a Sound Sensor to record the initial pulse of sound and its echo. Calculate the speed of sound based on the overall distance traveled and the round-trip time.

Featured Equipment

Resonance Air Column

Resonance tube with plunger, node markers and detachable stands for performing waves and sound experiments.

550 Universal Physics System

Universal 550 Physics Experiment Bundle

This system provides a complete set of labs for mechanics, heat, light, sound, and electromagnetism.

Sound Sensor

Sound Sensor with Microphone

The Sound Sensor houses a sensitive microphone designed to display audio waveforms of sound levels between 45 and 100 dB.

550 Universal Interface

550 Universal Interface

The 550 is fast, powerful, and incredibly affordable. It offers half the ports and many of the same features as our 850 Interface in a smaller package.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
