Tuning Fork Set of 8 – Welch
Product Code : SCL-EAE-11124
Quick answer: This Welch-type set of 8 tuning forks is used to show students that sound comes from vibration and that pitch depends on frequency. With a resonance tube or box it supports resonance work and speed-of-sound estimates, and pairs of forks can demonstrate beats. Each fork is sounded by striking it gently on a soft pad. Lab Exports manufactures it in Delhi for schools, colleges and universities.

Experiments with the tuning fork set
Sound is a longitudinal wave: as the prongs of a fork move apart and together, they push and pull on the air, producing compressions and rarefactions that travel outward. Touching the stem of a sounding fork to a bench top makes the sound louder, because the larger surface sets more air vibrating, a simple way to show forced vibration.
With a set of eight, several classic practicals become possible. Students can put the forks in order of pitch by ear, find the resonating length of an air column for each fork, or sound two forks together and count beats. For the first resonance of a tube closed at one end the resonating length is about v/(4f), so a graph of length against 1/f is a straight line with gradient v/4, giving the speed of sound.

Frequently asked questions
What experiments can be done with a set of 8 tuning forks?
Comparing pitch and frequency, finding resonating lengths of an air column to estimate the speed of sound, and demonstrating beats with two forks of close frequency.
Why does touching a sounding fork's stem to a table make it louder?
The table top is forced to vibrate at the fork's frequency and, having a much larger area, sets more air in motion, so the sound is louder, though it dies away sooner.
