Description

This heavy duty electric tuning fork is used to show the relationships between frequency, length, tension and mass or learn about Melde's standing wave experiments. An electromagnet drives the fork to a sustained frequency of approximately 80 Hertz (Hz). One prong of the tuning fork has a captive knurled thumbscrew for performing Melde's experiment. Amplitude of the tuning fork vibrations is 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.
