A student is using a resonance tube and determines that three resonances occur at distances of
L1 = 0.170 m,
L2 = 0.497 m,
and
L3 = 0.844 m
below the open end of the tube. The frequency of the tuning fork used is
5.12 102 Hz.
What is the average speed of sound from these data? (Enter your answer to three significant figures.)
vavg = ____m/s
