3B10.10 - Wave Demo - Spring on Wall and Rope

Code Number:
3B10.10
Demo Title:
Wave Demo - Spring on Wall and Rope
Condition:
Excellent
Principle:
Wave Motion
Area of Study:
Acoustics, E & M

Disclaimer

Equipment:
Wall Spring (10 ft and 6 ft) and 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.
