Tuning Forks on Resonance Boxes – Pair (Beat Frequency Demonstration)

This Pair of Steel Tuning Forks on Resonance Boxes is designed for clear, engaging demonstrations of beat frequencies, resonance, and the relationship between frequency and sound waves. Each tuning fork is mounted on its own wooden resonance box, amplifying the sound and making the effects easy to hear in a classroom setting.

One fork includes an adjustable mass slider, allowing its frequency to be shifted slightly from the nominal 426.6 Hz. When both forks are struck together, the slight difference in frequency produces a clearly audible beat pattern, enabling students to explore interference, superposition, and wave phenomena with precision and clarity.

This apparatus is ideal for teaching wave physics, resonance, and acoustic principles at secondary and post‑16 levels.
