Condition :	Excellent
Principle :	Wave Motion
Area of Study :	Acoustics, E & M
Equipment :	Wall spring (10 ft.) (6 ft.), Ropes.
Procedure :	Attach the rope and spring to the hooks that are mounted on the lecture room walls. Pull on the spring and have someone hit the spring with a rod near one end to create a pulse. Put a 5 foot rope on the end of the spring to make a non-fixed end.
