Adjustable Tuning Fork – Variable Frequency C128–B240

Adjustable tuning fork with sliding weights for variable frequency sound demonstrations from C128 to B240.

This versatile acoustics teaching tool allows students to explore pitch, vibration, resonance, and wave frequency in a hands-on way. By sliding the adjustable weights along each prong, teachers can demonstrate how changing mass affects frequency and tone. Ideal for secondary physics classrooms, NCEA sound investigations, and general wave demonstrations, it provides clear, audible tones across a practical musical range for engaging and repeatable experiments.
