2. Electromagnetic spectrum - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_spectrum

   The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and ...

3. E band (waveguide) - Wikipedia

   en.wikipedia.org/wiki/E_band_(waveguide)

   The waveguide E band is the range of radio frequencies from 60 GHz to 90 GHz in the electromagnetic spectrum, [1] [2] corresponding to the recommended frequency band of operation of WR12 waveguides. These frequencies are equivalent to wave lengths between 5 mm and 3.333 mm. The E band is in the EHF range of the radio spectrum

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. Ultra low frequency - Wikipedia

   en.wikipedia.org/wiki/Ultra_low_frequency

   Ultra low frequency (ULF) is the ITU designation [1] [2] for the frequency range of electromagnetic waves between 300 hertz and 3 kilohertz, corresponding to wavelengths between 1,000 to 100 km. In magnetosphere science and seismology , alternative definitions are usually given, including ranges from 1 mHz to 100 Hz, [ 3 ] 1 mHz to 1 Hz, [ 4 ...
