PURPOSE: Useful for obtaining a reasonably good impedance match between the two large segments of the Shive machine.

DESCRIPTION: Connect the tapered transformer between the two large wave machine segments. Inserting this reduces the impedance mismatch and allows a continuous sine wave to pass from one medium into the other with minimal reflection, as seen in the photograph at the left. At the right is a close-up of the tapered transformer.

SUGGESTIONS: The manual written by Shive contains excellent information on both the theory and the use of the wave machine; copies are available in the Lecture-Demonstration office.

EQUIPMENT: Two large segments of Shive Wave Machine with tapered transformer.

SETUP TIME: None.
