Sonometer, 3 Wire Pattern Manufacturer,Supplier and Exporter in India

Sonometer, 3 Wire Pattern (Product Code: SLE/PHY/296) is a stretched-string apparatus used to study the laws of vibrating strings and compare frequencies in school and college physics laboratories. Its hollow wooden resonance box, 1290 x 130 x 110 mm, carries millimetre scales, a pulley-loaded wire and a 100 N spring balance for measured tension. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 3 Wire Sonometer Used For?

The sonometer lets students verify the three laws of transverse vibration: frequency varies inversely with vibrating length, with the square root of tension, and inversely with the square root of mass per unit length. On this pattern the spring balance sets a measured tension on one wire through the wing nut, while the pulley wire is tensioned by hanging masses, so two methods of applying tension can be compared on one box. A small paper rider on the wire jumps off at resonance when a sounding tuning fork is pressed against the box.

Typical practicals include finding the frequency of an unknown tuning fork, comparing two forks, and plotting vibrating length against 1/f. Move the bridges slowly and read lengths from the millimetre scale at the bridge edges. Release tension at the end of each session so the wires and the spring balance are not left under load, and keep the wooden box dry so its resonance stays consistent.

What to Specify When Ordering

• Number of Sonometer, 3 Wire Pattern sets for your laboratory.
• Tuning fork sets and slotted masses for loading the pulley wire, if needed.
• Spare wire requirements for restringing.
• Whether the order is for your own institution or for resale as a dealer or importer.

OEM Manufacturer

This sonometer is produced by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is the OEM (original equipment manufacturer) rather than a reseller. The wooden resonance box is built, fitted with its scales, pulley, bridges and spring balance, and assembled at the company’s own licensed factory at Saha, Ambala, Haryana, India.

Schools, colleges, government institutions, dealers and importers buy direct from the factory, and quotations come straight from the people who make the apparatus. Ask us about replacement wires, bridges or balances and about repeat orders for additional laboratories. More about the company is on our profile page.

Frequently Asked Questions

What size is the Sonometer, 3 Wire Pattern?
The Sonometer, 3 Wire Pattern is built on a hollow wooden resonance box measuring 1290 x 130 x 110 mm. Millimetre scales run between the fixed bridges, so vibrating lengths can be read directly without a separate rule.

How is tension applied on the Sonometer, 3 Wire Pattern?
On the Sonometer, 3 Wire Pattern, one end carries a spring balance reading 100 N x 5 N, with a wing nut for fine adjustment of tension. Another wire passes over a pulley and is tensioned by loading it with masses as desired.

Which experiments can be done with the Sonometer, 3 Wire Pattern?
The Sonometer, 3 Wire Pattern is used to verify the laws of vibrating strings, find the frequency of a tuning fork, compare frequencies and investigate how length and tension affect pitch, using a paper rider or ear to detect resonance.
