  • Re: What is the resonant frequency of granite or quartz?

    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. All of what we call "granite" does not have constant physical characteristics. That is, not all granite has the same

  • Crystal oscillator Wikipedia

    A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a constant frequency. This frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters

  • Vibration and Resonant Frequency of Water

    The resonant frequency of tungsten is the visible light frequency. That`s how the electric light bulb works. The natural resonant frequencies of molecules of water and organic substances are within the far-infrared (FIR) wave frequencies (wavelength of 5 to 15 microns); therefore, water and organic substances absorb energy easily from this radiated FIR wave. Since it is their resonant
