title: Shive Wave Machine
aka:  Bell Labs torsional waves

Description:
Bars are mounted on a torsion rod.  Raising the end of the bar on either end will cause a pulse to travel along the bars in a nice slow speed.

Questions?
   What happens to a single pulse when it hits a fixed or free end?  
   What happens when two pulses interact?  Note that the pulse reflected from the end interacts with the incident pulse.
   Can the instructor make standing waves?
