After partially filling the resonance tube with water sound a tuning fork of known frequency at the tube's open upper end. Then the water level can be adjusted until the air in the tube resonates at the same frequency as the tuning fork increasing the volume of sound. The apparatus consists of a water reservoir glass resonance tube marked in increments of 1mm a support stand and two clamps to hold the tube in position. Dimensions: 7-1/2" x 5" x 3'.
