One-string metallic sonometer
Product Code : SCL-ES-12776
Quick Answer: The One-String Metallic Sonometer has a metallic resonating body with one stretched string and is used to verify the laws of transverse vibration of strings. Students vary the vibrating length and tension to see how frequency depends on length, tension and mass per unit length.

About This Product
In the string-vibration practical, a tuning fork of known frequency is sounded near the body and the bridge gap is changed until the paper rider jumps or falls at resonance. Repeating the reading at different lengths and tensions lets a class check how the frequency of a string depends on each.
Frequently Asked Questions
How is resonance detected on the One-String Metallic Sonometer?
A small paper rider is placed on the string and a vibrating tuning fork of known frequency is brought near the body or bridge. When the vibrating length is right, the rider vibrates strongly or falls off.
Which laws can be verified with this sonometer?
The laws of transverse vibration of stretched strings: how frequency depends on the vibrating length, the tension and the mass per unit length of the string.
