Quick Answer: The Speed of Sound Kit gives a direct method of measuring the speed of sound, using a Fast Timer that starts and stops to microsecond accuracy as a sharp sound passes two ceramic microphones.
Last updated: October 2026
Key Features
Fast Timer with timing to microsecond accuracy
2 ceramic microphones start and stop the timing as the sound passes
Mini claw hammer and metal plate for making a sharp sound
Fast Timer also works with mechanical start/stop gates, for example in measuring g by free-fall
About This Product
A tap of the mini claw hammer on the metal plate makes the sharp sound needed for the test. Timing starts as the sound passes one microphone and stops as it passes the other, so the speed of sound can be measured in the classroom. Away from this experiment, the Fast Timer can be used in many other experiments.
Frequently Asked Questions
Q1. Can the Fast Timer be used for other experiments? Yes. When used with mechanical start/stop gates it has many other applications, for example measuring g by free-fall.
