3 Wire Pattern Sonometer
Product Code : JA-SW-7652
The 3 Wire Pattern Sonometer (SKU JA-SW-7652) is a sonometer for studying the vibration of stretched strings. It is built on a hollow wooden resonance box of 1290 × 130 × 110 mm with millimetre scales between fixed bridges over which the wires are stretched; one wire passes over a pulley and can be loaded as desired, and a 100 N spring balance with wingnut adjustment sets and measures the tension of another. JaincoLab supplies this three wire sonometer to school and college physics laboratories.
Specifications
The sonometer has a hollow wooden resonance box of 1290 × 130 × 110 mm, scales divided in millimetres between fixed bridges, a wire passing over a pulley for loading with weights, and a spring balance reading 100 N × 5 N at one end whose tension is finely adjusted by a wingnut.

Sonometer experiments with the three wire pattern
The 3 wire sonometer is used to verify the laws of vibrating strings: students vary the vibrating length between bridges, the tension set on the spring balance or by weights on the pulley wire, and compare wires, then find the length that resonates with a tuning fork to determine its frequency.
- Verifying the law of length for a vibrating string
- Verifying the law of tension using the spring balance or pulley weights
- Finding the frequency of a tuning fork by resonance
- Comparing the vibration of different wires side by side
- Class 11 and 12 and B.Sc practicals on stationary waves in strings
