TSA Sound SwitchesThese Sound Switches connect to the TSA (not included) and can be used to measure the speed of sound in air and through solids
Because TSA can measure time intervals to 1/100 of a milliseconds it is possible to put the switches a short distance apart in the lab and measure how long time takes to travel that distance
The quality of the sound source is important
A clean, fast rising pulse can be best generated by hitting an empty bottle with the plastic handle of a screwdriver
When the sound arrives at the first switch it starts the Fast Timer in the TSA and when it arrives at the second switch it stops the timer
The switches are latched
The Sound Switches enable pupils to quickly and easily measure the speed of sound in air and in solids
The TSA is not included, but is available to purchase separately
