NARRATIVE
                The period of a pendulum is dependent upon the square of the length and is independent of the mass.

            Two pendulum with lengths of a ratio of 1:4 may be set up on the device for showing resonance.  These pendulum have the same masses. Two pendulum of the same length but of different masses may be constructed from any of several balls available.
