Resonance Rod Apparatus

Concept Overview:

Visual demonstration of resonance

Lecturer Procedure

Step(s) to FollowExpected Result
  1. Rock apparatus back and forth using the board attached to the end.
  2. Find the rhythm of the colored tip to which you would like resonance to occur.
  3. Rock with that rhythm
The colored tips experiencing resonance will have a significantly greater displacement

Alternately:

  1. Pull one cube to the side and release
The other cube of the same color will begin to oscillate with the same frequency and a greater displacement than the other cubes, thus showing resonance
