Concept Overview
Production of a longitudinal (compression) wave for ease of visualization.
Lecturer Procedure for Demonstration
| Steps to Follow | Expected Result |
|---|---|
| Push a coil near 1 end horizontally and quickly bull it back to equilibrium. | A longitudinal (compression) pulse is created. |
| Move a coil horizontally several times, with force. Carefully choose the timing to create a rhythm. | A standing longitudinal (compression) wave is produced. |
Historical References; Taken from original work of Percy H. Carr, 1970
“Usually as stored the ends of the spring are fastened firmly to the mounting stand and make excellent wave reflectors. Even a free end is an excellent reflector, but you will have to free an end from the fastening if you desire to show this property.”
