This simple apparatus clearly demonstrates the principles of resonance without requiring a water column or other apparatus. Using the included 512 Hz tuning fork as a sound source, the inner tube slides inside the outer one and the student finds the point of loudest sound. By applying a constant end correction, the wave length in air is easily calculated from the combined overall length of the tube set. The tubes adjust from 25 to 38 centimeters (approximately 9-4/5 x 15inches), which will tune over a range of approximately 452 Hz to 585 Hz at room temperatures. A 50-millimeter (2-inch) plug is included to close end.
