Resonance Horns with matching tuning forks

 

Code Number: 3D30.21

Demo Title: Resonance Horns - Conical Pipes

Condition: Excellent

Principle: Resonance Cavities

Area of Study: Resonance

Equipment: 

Resonance Horns with matching tuning forks.

Procedure:

The resonance horns are stamped with the frequencies that can be matched to the corresponding tuning fork.  The whole point is that the resonance horn should isolate and resonate at the fundamental frequency of the matching tuning fork.
