SPEED OF SOUND KIT
Offers the most direct means of measuring the speed of sound. Comprises a fast timer, two ceramic microphones, a small hammer and anvil. The microphones are placed a distance apart, and a sharp noise is made at the one microphone. Timing is started and stopped when the sound reaches the second microphone. The result is shown on the LCD display. The fast timer can also be used for determination of 'g' and can also accept inputs from two light gates, or mechanical switches for other experiments.
