  • The Resonance Apparatus allows students to investigate the resonant behavior of an enclosed air column when it is stimulated by an external sound source.
  • The air column lengths for multiple resonances at various frequencies can be found and the resulting data can be used to determine the speed of sound.
  • A cylindrical acrylic tube is mounted vertically on a stand base and rod.
  • The tube is open at the top and closed at the bottom by a rubber stopper with a hose barb.
  • A scale is printed along the length of the tube.
  • Flexible tubing connects the bottom of the tube to a large reservoir.
  • The reservoir and tube are partially filled with water, creating an air space in the tube above the water level.
  • The length of the space can be varied by adjusting the height of the reservoir on the support rod.
  • A suitable sound source, which can be a tuning fork (not included) or a tone generator (not included), is held close to the mouth of the tube while the length of the air column is varied.
  • Points of resonance where the sound in the tube becomes louder can be heard and measured.
  • The sound level may also be recorded for later analysis using probeware.
