Tuning Forks with Resonance Boxes – Superior Model, Set of 2 (256 Hz Adjustable)

Superior tuning fork set with resonance boxes for advanced resonance and beat frequency demonstrations.

This premium classroom acoustics apparatus features two extra heavy aluminium tuning forks mounted on individual resonance boxes, producing a longer audible vibration than standard forks. Designed for secondary physics and senior science investigations, the set allows students to observe resonance, sympathetic vibration, and beat frequency phenomena in a clear and measurable way. One fork is fixed at 256 Hz while the second includes an adjustable sliding weight, enabling controlled frequency variation for beat experiments and resonance alignment.
