- An electromagnet drives the fork to a sustained frequency of approx. 80Hz.
- One prong of the tuning fork has a captive knurled thumbscrew for performing Melde’s experiment.
- Universal binding posts are finished to provide electrical power from an external source of 2 to 6 volts DC.
This electric tuning fork is used to show the relationships between frequency, length, tension and mass or learn about Melde's standing wave experiments with this heavy duty electric tuning fork. An electromagnet drives the fork to a sustained frequency of approx. 80Hz. 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.
