Speed of Sound Kit KIT

This kit includes everything you need to measure the speed of sound in the classroom.

• Direct method for measuring time taken for sound to travel a known distance

• The Fast Timer can be used in many other experiments

This kit provides a direct method to measure the speed of sound. Timing to microsecond accuracy is started and stopped as sound passes the microphones - see the experimental diagram. A small hammer and metal plate is included in the kit to make the necessary sharp sound. The Fast Timer, when used with mechanical start/stop gates, has many other applications e.g. in the measurement of g by free-fall.

The kit consists of:

• Fast timer

• 2 x Ceramic microphones

• Mini claw hammer

• Metal Plate
