Abstract:
The period of a simple pendulum was measured with a precise timing system consisting of a phototransistor, the output of which triggered the sweep of an oscilloscope which, at the same time, displayed the standard radio time signal of JJY from Tokyo, Japan. The oscilloscope display was photographed with a Polaroid camera and the period was calculated. The method is simple, does not require elaborate pieces of equipment, and still gives accuracy to ± 4 parts in 106.
