  2. Royal Rife - Wikipedia

    en.wikipedia.org/wiki/Royal_Rife

    Royal Raymond Rife (May 16, 1888 – August 5, 1971) [1] was an American inventor and early exponent of high-magnification time-lapse cine-micrography. [2] [3]Rife is known for his microscopes, which he claimed could observe live microorganisms with a magnification considered impossible for his time, and for an "oscillating beam ray" invention, which he thought could treat various ailments by ...

    In closing, I would like to say what most people are talking about as a Rife machine or Rife frequency, is actually a Crane machine or Crane frequency. Rife's original frequencies from his lab notes started at 400,000 Hz and went to 13,000,000 Hz. Crane's frequencies are at 20 to 10,000 Hz, and Clark's Frequencies are from 80,000 to 800,000.

    These were limited to frequencies of 0.1 – 2 MHz, called "longwave" diathermy. The current was applied directly to the body with contact electrodes, which could cause skin burns. In the 1920s the development of vacuum tube machines allowed frequencies to be increased to 10 – 300 MHz, called "shortwave" diathermy. The energy was applied to ...

  5. Radio frequency - Wikipedia

    en.wikipedia.org/wiki/Radio_frequency

    Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz.

    The FCC has restricted the frequencies allowed for medical treatment, and most machines in the US use 27.12 MHz. [26] Shortwave diathermy can be applied in either continuous or pulsed mode. The latter came to prominence because the continuous mode produced too much heating too rapidly, making patients uncomfortable.

  7. Healy (bioresonance device) - Wikipedia

    en.wikipedia.org/wiki/Healy_(bioresonance_device)

    Energy medicine devices are a class of pseudoscientific devices that originated with the work of Royal Rife, claiming to work via transferring energy to a person's energy field. The Healy claims to work using electricity to find a user's "personalized frequencies", an idea that has no scientific backing or mechanism. [3]

  8. Radio spectrum - Wikipedia

    en.wikipedia.org/wiki/Radio_spectrum

    Radio waves are defined by the ITU as: "electromagnetic waves of frequencies arbitrarily lower than 3000 GHz, propagated in space without artificial guide". [5] At the high frequency end the radio spectrum is bounded by the infrared band. The boundary between radio waves and infrared waves is defined at different frequencies in different ...

  9. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    Frequencies observed in astronomy range from 2.4 × 10 23 Hz (1 GeV gamma rays) down to the local plasma frequency of the ionized interstellar medium (~1 kHz). Wavelength is inversely proportional to the wave frequency, [ 1 ] so gamma rays have very short wavelengths that are fractions of the size of atoms , whereas wavelengths on the opposite ...
