High frequency - Wikipedia
WEBHigh frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).
Electromagnetic spectrum - Wikipedia
WEBThe 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 gamma rays.
Electromagnetic Spectrum – The Physics Hypertextbook
WEBElectromagnetic waves span a spectrum that ranges from long wavelength, low frequency radio waves to short wavelength, high frequency gamma rays.

WEBThe quantity known as the wave’s frequency refers to the number of full wavelengths that pass by a given point in space every second; the SI unit for frequency is Hertz ( Hz) , which is equivalent to “per seconds” ( written as 1 s or s − 1) .
Very high frequency - Wikipedia
WEBVery high frequency ( VHF) is the ITU designation [1] for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.

What is High Frequency (HF)? - Definition from Techopedia
WEBOct 29, 2015 · High frequency (HF) is an electromagnetic frequency defined by the International Telecommunications Union (ITU) for radar and radio communications. It operates in a range of three to thirty MHz and as the wavelengths spread over ten to one hundred meters, it is also known as decameter wave and designated as band 7.
