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.
