0 1 Figure 1 shows apparatus used to measure the speed of sound in a steel rod.
Figure 1
The steel rod is suspended from a beam using rubber bands.
When the hammer is in contact with the end L of the steel rod, a circuit is completed
and the signal generator is connected to the oscilloscope.
Figure 2 shows the waveform then displayed on the oscilloscope.

When the hammer box hits end L, a sound wave travels along the steel rod and is
reflected at end R.
When the wave returns to L the rod bounces away from the hammer and the circuit is
broken.
Figure 3 shows the waveform produced by the brief contact between the hammer
and L.
Note that the waveform has now been centred vertically.
