The issue is what is a “radio” frequency. Household AC current is 60Hz, a wavelength of 50,000 kilometer.

Heinrich Hertz’s production in 1888 of what are now called radio waves, his verification that these waves travel at the same speed as visible light, and his measurements of their reflection, refraction, diffraction, and polarization properties were a convincing demonstration of the existence… Radio wave frequencies range from Extremely Low Frequencies (ELF) 3 kilohertz (kHz) to Extremely High Frequencies (EHF) 300 gigahertz (GHz) as shown in infographic above (larger version at bottom).

EHF are often called the millimeter band because its wavelengths range from 1 to 10 mm.





Thanks!If employees need to talk to clients on cell phone,...WilsonPro signal boosters are on sale for the lowest price,...Types of Frequencies and Wavelengths in the Radio Frequency Spectrum5G Frequency Spectrum Usage by 4 major USA Carriers:The following are preliminary disclosed 5G frequencies and subject to change in future: For example, 15 Hz (low frequency) has a wavelength of over 3,000 miles, while 300 GHz (high frequency) is only 1 mm. The brief account of familiar phenomena given above surveyed electromagnetic radiation from low frequencies of ν (radio waves) to exceedingly high values of ν (gamma rays). Going from the ν values of radio waves to those of visible light is like comparing the… Wavelength is inversely proportional to frequency.

Therefore, high frequencies can travel at faster speeds but can go only short distances.

See the chart of Elecromagnetic Spectrum from Wikipedia, below. …the different regions of the spectrum are described in this section.… The electromagnetic spectrum.



The entire electromagnetic spectrum, from the lowest to the highest frequency (longest to shortest wavelength), includes all radio waves (e.g., commercial radio and television, microwaves, radar), infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.







Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.This article was most recently revised and updated by Both types will require a You totally forgot about VLF which is a designation that has been around since the end of WWII.“Therefore, high frequencies can travel at faster speeds (…) low frequencies travel at slower speeds (…).”Good Info.

This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave or the frequency of a radio wave.

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X …

The longest wavelength corresponds to long wave radio, I think the longest used is about 2000 meters.

Ultra High Frequency (UHF) band has a frequency range of 300 MHz to 3 GHz. Been looking for concise frequency/wavelenth spectrum info for a bit. Any wavelength can be generated. On other hand, low frequencies travel at slower speeds and can go longer distances.This is why a lower number 3G frequency example 800 MHz UHF band network phone (providing slower downloads, higher latency) would require a cell transmitter or cell tower within 2 miles to connect whereas a higher number 5G frequency example 39 GHz EHF band network phone (providing faster downloads, lower latency) would require a cell transmitter within each block or roughly between every six houses.
UHF spectrum is also being used by some Carriers for 5G.
