Learn about Melde's standing wave experiments with this 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 adjusted screw. Universal binding posts are finished to provide electrical power from an external source of 2 to 6 volts DC, required but not included.
