Experiment with springs, oscillations, and wave theory! Mount the demonstration spring onto the vibration generator to learn about oscillation and resonance. The vibration generator produces a low frequency mechanical oscillation with a range of 0.5 to 5,000 Hz. Includes vibration generator and demonstration spring. A ring stand and clamp, signal generator, and banana plugs are needed but not included. Audio generator not included (SB46992M). Additional oscillation experiments can be performed using Chladni plates, Kundt’s tubes, cords, and more. Grade 8 and up. WARNING: Choking Hazard. Small Parts. Not for children under 3 yrs.
