Mar 11, 2011· Furthermore, the tuning fork is made of quartz with just the right orientation of its crystal axis relative to the tuning fork so that its resonant frequency changes very little with temperature. This means it can be counted on to resonate at one exact frequency (to at least a part in 10 6 ), that frequency being 32,768Hz which is equal to 2 15 .

Every chakra, every organ, every bone, every tissue, every cell has its own resonant frequency, its own sound. Together, they create a unified or composite frequency, with its own sound, like the instruments of an orchestra coming together. Ideally, the individual …

A tight string will act "stiffer" and have a higher frequency of resonance. With the quartz resonators you mention, thin slabs of quartz are cut to a thickness that makes the resonance occur at a specific frequency chosen by the manufacturer. There is no one "magic" frequency at which quartz will oscillate. Granite is even more difficult.

Resonance, An object free to vibrate tends to do so at a specific rate called the object's natural, or resonant, frequency. (This frequency depends on the size, shape, and composition of the object.) Such an object will vibrate strongly when it is subjected to vibrations or regular impulses at a frequency equal to or very close to its natural ...
