Tuning Fork Resonance Experiment Kit

Product Code : SCL-PL-12130

Tuning Fork Resonance Experiment Kit (SKU SCL-PL-12130) pairs two matched 440 Hz tuning forks on open-ended wooden resonance boxes to show sympathetic resonance: strike one fork, silence it, and the other keeps sounding. A clamp-on mass slider also lets teachers demonstrate beats. It is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, which quotes and dispatches it directly to institutions and trade buyers.

Specifications

Both forks are aluminium alloy, tuned to 440 Hz (A4) within a stated tolerance of ±0.5% at room temperature, and screw into their boxes on threaded steel stems so they can also be used without the box. The seasoned pine boxes are hollow, open at one end, and stand on rubber isolation feet.

Applications and Experiments for the Tuning Fork Resonance Kit

The kit shows that a vibrating body can set a second body of the same natural frequency vibrating through the air. Adding the mass slider detunes one fork so that both sound together with beats. It suits Class 9 and Class 11 sound topics and B.Sc. acoustics demonstrations.

• Class 9 science: sound as a mechanical wave that travels through air.
• Class 11 physics: natural frequency, sympathetic resonance and beats.
• Amplification of sound by the resonating air in the open boxes.
• B.Sc. lectures: beat frequency as the difference of two nearby frequencies.

Standard Scope of Supply

The kit contains two calibrated 440 Hz aluminium tuning forks, two tuned wooden resonance boxes, one rubber-headed striking mallet, an adjustable prong mass slider for creating a frequency offset, and an illustrated experiment guide with data sheets.

Packing, MOQ and Lead Time

Request a price for a single kit or for several kits for a department, and the quotation will show packing, delivery time and cost for that quantity. Other physics lab equipment in India, such as tuning fork sets or a resonance tube, can be added.

Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. Enquire from the contact page or add the kit to the enquiry cart; school tenders can be sent via the lab tender page.

Frequently Asked Questions

How does the kit show sympathetic resonance?
Sound from the first fork travels across the gap into the open face of the second box and drives the matching fork at its own natural frequency of 440 Hz, so it keeps sounding after the first is damped.

How are beats produced?
Clamp the mass slider onto one prong. The added mass lowers that fork’s frequency slightly, and striking both forks together gives a rhythmic rise and fall in loudness.

Can the forks be removed from the boxes?
Yes. Each fork screws into its box on a threaded steel stem, so it can be taken off and struck on its own for handheld tests.

Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies, a science apparatus manufacturer in India, makes the kit at its own factory in the HSIIDC Industrial Area of Saha, Ambala, and prepares every quotation and dispatch itself.
