Differential Tuning Fork Set
Investigate Beat Phenomena
What happens when two mounted tuning forks sound at different frequencies instead of identical sympathetic vabrations of the 84570 set? Your students explore this fascinating concept with a set of 2 resonance boxes topped by extra-heavy Duratone brushed aluminum forks. They more than double the duration of audible bibration. One fork is weighted, so you can adjust it over a range of about 30Hz. To make matters more interesting, the forks are different lengths: 19.4cm vs. 17.5cm. Let the fun begin!
