    Product Description


    1.  Connect as shown.  Position the vibrator so that the circular wire rests on the overhead projector table and can be seen completely.
    2.  Set the function generator amplitude to not more that half scale before turning on.
    3.  Adjust t he generator frequency scale until you find a 3 node resonance.  (approx. 20 Hz)
    4.  Try other frequencies to obtain various  resonances.  (Try 60, 100, & 140 Hz)
