Speed of Sound Kit by Unilab KIT

This Speed of Sound Kit includes everything you need to measure the speed of sound in the classroom. The Fast Timer included 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 diagram in the product images). 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
Learning Outcomes
Key Stage 3 Physics – Waves: Sound needs a medium to travel, the speed of sound in air, in water, in solids
Key Stage 4 Physics – Forces and Motion: Speed of sound, estimating speeds and accelerations in everyday contexts
