¥ Simple to use ¥ Direct measurement ¥ Reliable Data This is an easy to use
piece of apparatus for determining the speed of sound in air by simply
measuring the time taken for sound to travel a known distance. The unit
contains two sensitive microphones connected by a long cable to control
circuity that will start and stop a Lascells millisecond timer. In use a sharp
sound is produced and the time taken to travel the distance between the two
microphones is recorded on the timer (not included). A single reading can be
used or the separation between the microphones can be varied giving a range of
readings which may be plotted on a graph. An alternative approach is to omit
the timer and monitor the outputs on a dual channel storage or PC
oscilloscope. The apparatus is supplied with a 9V PP3 battery, a 6 metre
connecting cable and full instructions. Dimensions (LxWxH): 115 x 70 x 110mm
(main unit) 70 x 70 x 110mm (remote microphone) Weight: 375g
