TUNING FORK ELECTRIC ,Each

Details

This electric tuning fork is used to demonstrate the relationships between frequency, length, tension, and mass or to conduct Melde's standing wave experiments. An electromagnet drives the fork to a sustained frequency of approximately 80 Hz. One prong of the tuning fork features a captive knurled thumbscrew for performing Melde's experiment. The amplitude of the tuning fork vibrations can be varied by means of a threaded adjustment screw. Universal binding posts are finished to provide electrical power from an external source of 2 to 6 volts DC.
