Question:
What was the approximate length of the tube?
A. \(0.35 \mathrm{~m}\)
B. \(0.70 \mathrm{~m}\)
C. \(1.4 \mathrm{~m}\)
D. \(2.8 \mathrm{~m}\)
A student investigator is measuring the speed of sound by looking at the time for a brief, sinusoidal pulse from a loudspeaker to travel down a tube, reflect from the closed end, and reach a microphone. The apparatus is shown in Figure IV.1a; typical data recorded by the microphone are graphed in Figure IV.1b. The first pulse is the sound directly from the loudspeaker; the second pulse is the reflection from the closed end. A portion of the returning wave reflects from the open end of the tube and makes another round trip before being detected by the microphone; this is the third pulse seen in the data.
