Tuning Fork Set
Product Code : SCL-PL-12133
Tuning Fork Set (SKU SCL-PL-12133) contains five forks: two at 256 Hz and one each at 320, 426.7 and 480 Hz, matching the notes C, E, A and B. Placed face to face, the two 256 Hz forks show sympathetic resonance, and one of them is adjustable. The set suits school and college sound practicals. Buyers ordering a school tuning fork set in India can have this one quoted by its manufacturer, Science Lab Supplies, at its Saha, Ambala factory, which also serves dealers and tender contractors.
Specifications
The five-fork set is laid out fact by fact in the table below. In short, the forks are mounted on a wooden resonance box and come with a striker; of the two 256 Hz forks one is fixed and the other adjustable, so resonance can be shown at a matched frequency and then with one fork set apart.

Applications and Experiments for the Tuning Fork Set
The set is built to show how sound energy passes through air from one vibrating fork to another of the same frequency. Its extra frequencies extend it to pitch and resonance-tube work, supporting Class 9 sound, Class 11 waves and B.Sc. sound practicals.
- Class 9 science: sound needs a medium and is transferred through air, contrasted with the mechanical model of the Wave Motion Powell’s Wave Demonstrator.
- Class 11 physics: natural frequency and sympathetic resonance with the matched 256 Hz pair.
- Comparing the matched pair with the adjustable fork set away from 256 Hz.
- Resonance tube and sonometer experiments at four different frequencies, or a fork as the sound source on the Law of Reflection of Sound Apparatus.
Standard Scope of Supply
The set comprises two 256 Hz tuning forks (one fixed and one adjustable), one fork each of 320, 426.7 and 480 Hz, mounting on a wooden resonance box, and a striker. Resonance tubes or sonometers for further experiments are separate items.

Frequently Asked Questions
Which frequencies are included in the Tuning Fork Set?
Two forks at 256 Hz (C) and one each at 320 Hz (E), 426.7 Hz (A) and 480 Hz (B), five forks in all, mounted on a wooden resonance box.
Why are there two 256 Hz forks?
The matched pair shows sympathetic resonance: face to face, one sounding fork sets the other vibrating. One of the pair is adjustable, so the two can also be compared when set apart.
Which experiments use the other three forks?
The 320, 426.7 and 480 Hz forks give extra known frequencies for resonance-tube and sonometer work, so results can be compared at more than one pitch.
Is Science Lab Supplies the manufacturer or a trader?
The five forks and their resonance box are made at Plot 448, HSIIDC Industrial Area, Saha, Ambala, so the set is quoted by Science Lab Supplies as its manufacturer, straight from its own works.
