Electromagnetic radiation is a transverse wave consisting of oscillating electric and magnetic fields. In a vacuum, the waves always travel at 300,000 km/s (671 million mph), but their wavelengths vary enormously. Gamma rays have tiny wavelengths, often smaller than an atom, while radio waves ...
Electromagnetic radiation, in classical physics, the flow of energy at the speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves and visible l
Electromagnetic Fields C.F. del Pozo, in Encyclopedia of Toxicology (Second Edition), 2005 Exposure to Weak-Intensity Nonionizing EMF Radiation in the 0–300 GHz Frequency Range Common sources of low-level exposure to electromagnetic fields are electric and magnetic powered transport (static fields)...
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
From the electric current of oscillating pairs, we obtain the energy spectrum of electromagnetic dipole radiation. This narrow spectrum is so peculiar that the detection of such radiation can identify pair production and oscillation in strong laser fields. We also obtain the energy spectrum of ...

George Bekefi and Alan H Barrett London: MIT Press 1978 pp xvi + 664 price £12.25 (paperback) As the title indicates, the subject matter of this book spans a wide range of subjects, from oscillators and wave motion, through electromagnetism and radiation, to light scattering and optics. ...
Electromagnetic radiation consists of alternating electric and magnetic fields (Fig. 3.1). The electric field vector is perpendicular to the magnetic field vector, and the direction of propagation is perpendicular to both. Radiation is often specified by its wavelength, which is the distance between ...
EMF Electric Fields EMF design consulting for human-generated electrosmog should involve Radio Frequency (RF) radiation, dirty electricity (high-voltage transients), low-frequency magnetic fields, and low-frequency electric fields. These four elements can be wrapped under the umbrella term, “electromag...
