Comments on "Speed of Sound in Metal Pipes: An Inexpensive Lab"
Blodgett, Earl D.
Physics Teacher, v47 n1 p31-32 Jan 2009
In a recent article Huggins outlines a very simple method of measuring the speed of sound in metal pipes by striking one end with a hammer and recording the transit time as the resultant pulse echoes back and forth. We immediately adapted this for use in an introductory laboratory where we are familiarizing students with the measurement of time-dependent signals, especially how to set trigger levels for transient capture. As we prepared to implement this in our situation, we made a few observations that others may find of value.
