Resonator Tube
NARRATIVE
This device
consists of a variable length closed ended pipe and a tuning fork. At certain lengths of
the tube, the reflected wave will interfere constructively with the incoming waves and
produce a louder sound. Pour enough colored water into the tube so that some water is in
the bottom of the can. Hold the vibrating tuning fork over the open end of the tube and
vary the length of the air column by raising and lowering the can. Locate positions of
resonance.
