Radio frequency is measured in units calledhertz(Hz), which represent the number of cycles per second when a radio wave is transmitted. One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second. In...

A radio wave has a frequency of {eq}7.9 \times 10^{10} {/eq} Hz. What is the energy (in J) of one photon of this radiation? Photon and its Energy Photons are descrete units or packets of energy of an electromagnetic wave. Each photon is...
The list according to the present invention is based on a cyclotron type interaction between a beam of electrons which are propagated between a gun has electrons 1 and a collector 3 and a high frequency field increasing in a structure resonant 2. It is characterizes mainly in that the beam ...
Electromagnetic radiation - Radio Waves, Frequency, Wavelength: Radio waves are used for wireless transmission of sound messages, or information, for communication, as well as for maritime and aircraft navigation. The information is imposed on the electr
The dielectric permittivity elements, evaluated in the paper, are suitable to estimate the wave dissipation by electron Landau damping (e.g. during the plasma heating and current drive generation) in the frequency range of Alfvén and fast magnetosonic waves, for both the large and low aspect ...
