To determine the frequency of an electrically maintained tuning fork by, 1. Transverse mode of vibration 2. Longitudinal mode of vibration Apparatus Electrically maintained tuning fork, fine thread, scale pan, weights and meter scale. Theory Speed of waves in a stretched string: A string means a wire or a fiber which has a uniform diameter and is perfectly flexible. The speed of a wave in a flexible stretched string depends upon the tension in the string and mass per unit length of the string. Longitudinal mode- In this arrangement the tuning fork is set in such a manner that the vibrations of the prongs are parallel to the length of the string.
