Condition :   Good  
Principle :   Simple Harmonic Motion  
Area of Study :  Acoustics
Equipment :   Barton's Pendula Apparatus
Procedure :   Adjust the large driving pendula to a desired height and set into motion.  After a few oscillations one of the pendula should be oscillating in resonance with the driving pendula, but almost 180 degrees out of phase.
