The sinusoidal vibrations of a tuning fork are made visible by means of a reflected light beam. The tuning fork is excited by compressed air, and can be rotated around its vertical axis. One of its legs carries a small mirror off which a laser beam is reflected onto the wall. By uniformly rotating the tuning fork, the time dependence of its vibration can be demonstrated.
