About This Product
The sonometer is used to verify the laws of transverse vibration of a stretched string: how frequency depends on vibrating length, tension and mass per unit length. With a tuning fork placed on the box, students find the resonant length and from it the frequency of the fork, and the same set-up can be used to find the frequency of AC mains.
Frequently Asked Questions
How is tension applied to the sonometer wire?
The wire passes over a pulley to a weight hanger, and slotted weights are added to the hanger to change the tension.
