Pendulum Wave

PENDULAR WAVE

Like giant cherries, these 16 pendulums surprise visitors by dancing together and producing what appears to be a random choreography.

With a regular oscillation, which repeats itself after a certain interval of time, pendulums have been used as instruments to measure the passage of time.

But how can we explain, for example, that different pendulum clocks on the same wall synchronize themselves?

The inclined bar, from which these ‘cherries’ are suspended by cables of different lengths, is like the wall on which the clocks are fixed. When released, the pendulums oscillate, and the tensions created in the bar cause a coordination between them.  The difference in lengths results in different periods of oscillation, which causes the pendulums to lose and regain phase cyclically, creating repeating patterns that resemble a wave.
