After the sound reflects off the opposite end of the tube, a graph will be displayed showing the initial sound and the echo. When you make a sound by snapping your fingers next to the opening, the computer will begin collecting data. The Microphone will be placed next to the opening of a hollow tube. In this experiment, you will use this technique with a Microphone connected to an interface to determine the speed of sound at room temperature. To use the same technique over short distances, you need a faster timing system, such as a data-collection interface.
You could then calculate the speed of sound. For example, if you were in an open field with a large building a quarter of a kilometer away, you could start a stopwatch when a loud noise was made and stop it when you heard the echo. One method you could use would be to time an echo. It is fast enough that measuring the speed of sound is a technical challenge. Compared to most things you study in the physics lab, sound waves travel very fast.
