Velocity of Sound Lab Experiment (Version 2) 1 Revised 3.22.2023 This lab will be turned in via a Lab Submission Quiz at the end of this lab. Introduction Compared to most things you study in a physics lab, sound waves travel very fast. It is fast enough that measuring the speed of sound is a technical challenge. One method you could use would be to time an echo. 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. You could then calculate the speed of sound. Can you think of exactly how you would do the calculation? To use the same technique over short distances, you need a faster timing system, such as a computer. In this experiment, we will use a microphone connected to a computer and a long hollow tube that is open at one end and closed at the other to determine the speed of sound at room temperature. A sound generated at the open end and its subsequent echo from the closed end of the tube are picked
