Catalog No. S82875

Description

• 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.
