Hi there, am reasearching colloidal/ionic silver and am actually investigating what this frequency is myself. This is the only mention sofar, will post more when I find something noteworty.

More specifically, Professor Rustum Roy of Penn State University engineered a specific size of the Guardian Silver elemental silver particle that resonates at 890 to 910 terahertz-the same frequency as blue germicidal lights used in hospitals for disinfection.
The silver nano particle emits a specific magnetic resonance-890-910 terahertz-which is selectively destructive to pathogens.

What are the methods for the production of ultrasonics?
Ultrasonics are sound waves with frequencies above 20khz. GALTON WHISTLE First they were produced by Galton.He called his Instrument the galton whistle.It consisted of a brass tube 2 mm in diameter and it was operated by blowing in a jet of high pressure gas.it consisted of a piston.on moving it the resonant cavity's length varied,on varying the length the resonant frequency too varied.Thus the resonant frequency depends on the length of the tube/pipe.But this could produce only up to 30khz. MAGNETOSTRICTION METHOD the main principle for this method is when a ferromagnetic rod made of material like iron or nickel is subjected to alternating magnetic field applied parallel to the rod,there will be a small elongation or contraction in its length.this change in length is proportional to the intensity of the magnetic field and nature of the ferromagnetic material. so the length of the rod changes for each half cycle of the alternating current which means the frequency will be twice the frequency of alternating current.. when the natural frequency of the rod matches with the frequency of the alternating current resonance occurs and amplitude will be maximum and ultrasonic waves are produced.In this method frequencies up-to 300KHZ can be produced. PIEZOELECTRIC OSCILLATOR The main principle of this is the inverse piezoelectric effect..according to the piezoelectric effect,when one pair of opposite faces of a crystal like quartz is subjected to pressure the other pair of opposite faces will develop electric charges and if the pressure is replaced by tension then the charges will be reversed..the inverse of this effect is that if the pair of opposite faces are subjected to alternating voltages then the other pair of opposite faces varies in its dimensions,i.e. it expands or contracts periodically thus generating elastic waves.When the natural frequency of the crystal matches with the frequency of the alternating current,resonance occurs and ultrasonic waves are produced.In this method frequencies upto 500MHZ can be produced.
What is the significance of the delta f over f parameter in frequency modulation?
The delta f over f parameter in frequency modulation is significant because it represents the frequency deviation relative to the carrier frequency. It determines the amount by which the frequency of the modulated signal varies from the original carrier frequency. This parameter is crucial in determining the bandwidth and quality of the modulated signal in frequency modulation systems.
The amount of frequency shift during modulation is called?
Frequency shift keying in digital communication and Frequency modulation in analog communication..........
What is the industrial frequency?
Industrial frequency, as used in Communications, aka the ISM band, is the frequency of signals between 900Mhz to around 2.4Ghz of encoded, compressed, or analog signals... industrial frequency can also refer to the common local power grid frequency (usually 60 or 50 Hz)
What happens in a circuit at resonant frequency?
what is resonant frequency
Is the resonant frequency the same as the natural frequency?
Yes, the resonant frequency is the same as the natural frequency.
How to find the resonant frequency of a room?
To find the resonant frequency of a room, you can use a sound frequency generator and a microphone to measure the frequency at which sound waves resonate the most in the room. This frequency is the room's resonant frequency.
Is the natural frequency the same as the resonant frequency?
No, the natural frequency and resonant frequency are not the same. The natural frequency is the frequency at which an object vibrates when disturbed, while the resonant frequency is the frequency at which an object vibrates most strongly when subjected to external forces.
What do you mean by resonant in power electronics?
Resonant in electronics circuit refer to tuning if the resonant condition arise it means the frequency where does the resonant arise is resonant frequency and the gain is highest on that particular frequency. it is widely used in receiver circuits.
What is the difference between the natural frequency and resonant frequency of a system?
The natural frequency of a system is the frequency at which it naturally vibrates when disturbed. The resonant frequency is the frequency at which the system vibrates with the greatest amplitude when subjected to an external force. The resonant frequency is usually close to the natural frequency, but not always the same.
What is the difference between resonance and resonant frequency?
resonance is the behavior of resonant frequency while resonant frequency is the cause of it. There are basically two types of resonance; Electrical and Magnetic. Resonant frequency is that particular frequency for a system for which the system performs its best. while the system at that particular situation can be called the system at resonance
What does resonant frequency mean?
Resonant frequency is the natural frequency at which an object vibrates most efficiently when disturbed. It is the frequency at which an object naturally oscillates without any external force. For example, pushing a swing at its resonant frequency will cause it to swing higher with minimal effort.
What is the difference between resonant frequency and natural frequency?
Resonant frequency is the frequency at which an object naturally vibrates when energy is applied, while natural frequency is the frequency at which an object vibrates without any external force.
At a frequency below the resonant frequency parallel circuit is?
A parallel resonant circuit has low impedance, when non resonant; however the impedance rises sharply, as the circuit comes to resonance.
What is the Resonant frequency of a piezoelectric transducer?
It's peak frequency
Do resonant frequency and natural frequency have the same meaning?
Yes.
