3B20.00: Longitudinal Waves in a Brass Rod
PURPOSE: To show wave energy transfer through an "L" shaped metal rod.
DESCRIPTION: The "L" shaped brass rod is clamped securely in a vise. A ball is suspended pendulum fashion so that it is in contact with the short segment of the rod. When the opposite end of the rod is struck sharply with a hammer, the wave energy travels through the rod and makes the ball swing.
SUGGESTIONS:
EQUIPMENT: "L" shaped Rod, Vise, Hammer, Stand, and small pendulum.
SETUP TIME: 2 min.
