Physics(Resonant Frequency)
"In sound applications, a resonant frequency is a natural frequency of vibration determined by the physical parameters of the vibrating object. This same basic idea of physically determined natural frequencies applies throughout physics in mechanics, electricity and magnetism, and even throughout the realm of modern physics."

"Mechanical resonance is the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system's natural frequency of vibration (its resonance frequency or resonant frequency) closer than it does other frequencies. It may cause violent swaying motions and potentially catastrophic failure in improperly constructed structures including bridges, buildings and airplanes. This is a phenomenon known as resonance disaster."

"Rife’s machine was built based on the work of Dr. Albert Abrams whom believed every disease has its own electromagnetic frequency (EMF)"

"frequencies at which simple viruses could be shaken to death."
"Moreover, it is unlikely that viruses will develop resistance to mechanical shaking, as they do to drugs."

Bioresonance(Resonant Frequency)
"Bioresonance is based on modern biophysics, which teaches us that every cell in our body resonates at a particular frequency which takes the form of electromagnetic field. Groups of cells in an organ or system have unique multiple frequency patterns which form a complex frequency make-up for the whole body."

"Bioresonance is a treatment that involves sticking electrodes onto the skin, which use electromagnetic waves to create a resonance able to detect unhealthy frequencies of the cells within our bodies, for example viruses and cancer cells. The device is then able to match the frequency and 'cancel out' the abnormality. The machine's electromagnetic waves are also believed to cure addictions like smoking cigarettes, apparently by cancelling out nicotine molecules in the body.
You might think that something as revolutionary would be a recent invention, but on the contrary, bioresonance is more than 40 years old."

Mortal Oscillatory Rate(Resonant Frequency)
"Rife Technology is based on the foundation of physics and electronic resonance.
Each microorganism (fungi, bacteria, virus, parasite, amoeba, mold, etc.) has a unique and specific frequency (or Mortal Oscillatory Rate). When you transmit more of this same frequency to the microorganism, it causes structural stress, and the pathogen is disabled or dies. The Rife machine generates resonance waves that destroy harmful pathogenic organisms without doing any harm to the rest of the body."

Luminescence(Resonant Frequency)
"The light, which contains the carrier and a mixture of selected signals in the UV range, stimulates the biological material in the Somatoscope to the point that the specimens give off their own light. (Rife referred to this as luminescence.) This is the key to the ultra-high resolution that has been achieved by Gaston Naessens."
http://www.rexresearch.com/naessens/naessens.htm
"He illuminated the microbe (usually a virus or bacteria) with two different wavelengths of the same ultraviolet light frequency which resonated with the spectral signature of the microbe. These two wavelengths produced interference where they merged. This interference was, in effect, a third, longer wave which fell into the visible portion of the electromagnetic spectrum. This was how Dr. Rife made invisible microbes visible without killing them, a feat which today's electron microscopes still cannot duplicate."
