Code Number: 3D32.22

Demo Title: Edge Tone Generator

Condition: Excellent

Principle: Edge Tones

Area of Study: Oscillations & Acoustics

Equipment:

Edge Tone Generator.

Procedure:

Turn on the compressed air until a fairly high flow rate from the slit is achieved. Adjust the wedge until an edge tone is produced. Adjusting the slit width will also produce different edge effects.
