Differential and Sympathetic Tuning Forks
Physics Educational Materials
Waves and Oscillations Learning Activities
These large alloy tuning forks are designed to demonstrate resonance, beat frequency, and sympathetic vibration.
- Frequency: 256Hz
- Moveable Mass Changes Frequency
- Forks Demonstrate Resonance, Beat Frequency, and Sympathetic Vibration
Each fork has a frequency of 256Hz. One fork has a movable mass to change the frequency. The closer the frequency is to the other tuning fork, the slower the beat pattern.
Students can see the beat patters using a probeware microphone. Assembly is required.
