Repetitive actions as encountered in the fading or flashing of LED intensity, the square-wave electrical signals for digital-logic clocks, electromagnetic waves, alternating current electricity, rotating motors, mechanical vibrations, sound waves, and pendulum or even planetary motions are recurring events in completely different contexts. However, all have a common feature in that there is a time period over which their individual cyclic actions repeat. A repeating event such as the vibration ...
