Aim: To measure the speed of sound in air.


Hypothesis: I think the speed of sound in air is.......
Method:
Set up the apparatus as shown.
Generate the sound using the two sections of wood.
As the sound passes the first sound sensor it starts the timer and as it passes the second sound sensor it stops the timer.
Measure the distance between the sensors and use the time recorded to travel this distance in the relationship v=d/t, to find the speed of sound.

Examples which illustrate that the speed of sound is greater than the speed of light?
