Light and other forms of radiation are described by field theory as electromagnetic waves. Therefore optics—the science of light—is a part of electromagnetism. The Maxwell equations describe the behavior of the electric field E(x, t) and magnetic field B(x, t). The time-dependent fields ...
Electromagnetic radiation - Spectrum, Wavelengths, Properties: 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
Polarization, property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way. Light waves are transverse: that is, the vibrating electric vector associated with each wave
In order to establish communication with the base station, the mobile phone as a radiation source emits electromagnetic waves to form an RF-EMF around it. The intensity of the radiation power of a mobile phone is generally defined as “Specific Absorption Rate” (SAR), to indicate the average...
How is electromagnetism created? Electromagnetic radiation is created when a charged atomic particle, such as an electron, is accelerated by an electric field, causing it to move. The movement produces oscillating electric and magnetic fields, which travel at right angles to each other, according to...
The notion of gravitational radiation as a radiation of the same level as the electromagnetic radiation is based on the theoretically proven and experimentally confirmed facts of the existence of stationary states of an electron in its gravitational field, characterized by the gravitational constant K ...
Abstract Here, we consider a topic which is absolutely central to the successful operation of all satellites and spacecraft, namely, the basic principles and fundamental concepts of visible light in particular and of electromagnetic radiation in general. Both the wavelike nature of light (the speed...
The electromagnetic properties of a medium are defined in terms of the dielectric constant (permittivity), ε, and the magnetic permeability, μ.
