Product Description

Objective: Record and evaluate oscillation of two identical coupled pendulums

The oscillation of two identical, coupled pendulums is distinguished by the period of oscillation and the beat period. The beat period is the interval between two points in time when one pendulum is swinging at its minimum amplitude. Both values can be calculated from the natural periods of oscillation for the coupled pendulums when the oscillations are in phase and out of phase.
