Used to investigate wavelength in air.
- This simple apparatus clearly demonstrates the principles of resonance without requiring a water column or additional devices
Using the included 512 Hz tuning fork as a sound source, students find 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 38cm which will tune over a range of approximately 452 to 585 Hz at room temperature. A 50mm plug to close one end is also included.
