Heavy-duty electric tuning fork. An electromagnet drives the fork to a sustained frequency of 80Hz. The tuning fork assembly and binding posts are mounted on a stable cast-metal base.
To show 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.
