Electromagnetic Radiation in a sentence

Dynamic magnetic fields may be a different issue, however; correlations between electromagnetic radiation and cancer rates have been postulated due to demographic correlations (see Electromagnetic radiation and health ).

Electromagnetic radiation Electromagnetic radiation is often described by its frequency—the number of oscillations of the perpendicular electric and magnetic fields per second—expressed in hertz.

However, when the absorbed electromagnetic radiation is intense, it is possible for one electron to absorb two photons ; this two-photon absorption can lead to emission of radiation having a shorter wavelength than the absorbed radiation.

Radio waves are a small part of a wider electromagnetic spectrum of waves, which all emit energy called electromagnetic radiation.

Electromagnetic radiation includes the far field part of the electromagnetic field around a transmitter.

Hertz's proof of the existence of airborne electromagnetic waves led to an explosion of experimentation with this new form of electromagnetic radiation, which was called "Hertzian waves" until around 1910 when the term "radio waves" became current.

The electromagnetic spectrum is the collective term for all known frequencies and their linked wavelengths of the known photons ( electromagnetic radiation ).

The electromagnetic spectrum is the range of all possible electromagnetic radiation frequencies.

The "electromagnetic spectrum" of an object has a different meaning, and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object.

The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields.

The non-ionizing portion of electromagnetic radiation consists of electromagnetic waves that (as individual quanta or particles, see photon ) are not energetic enough to detach electrons from atoms or molecules and hence cause their ionization.

To make matters worse for the team, Ultronshoot radiation and plasma beams, manipulate electromagnetic radiation into electricity, and even technoform (meaning he can transform his body into different weapons and other tools).

The new radiation detector, made of a gold-palladium mixture makes it easier to measure the strength of electromagnetic radiation in real time.

Dark matter is transparent to electromagnetic radiation and/or is so dense and small that it fails to absorb or emit enough radiation to be detectable with current imaging technology.

Eventually, the civilization would completely enclose the star, intercepting electromagnetic radiation with wavelengths from visible light downwards and radiating waste heat outwards as infrared radiation.

Radiation pressure implies an interaction between electromagnetic radiation and bodies of various types, including clouds of particles or gases.

Since the Maxwell theory of light allows for all possible energies of electromagnetic radiation, most physicists assumed initially that the energy quantization resulted from some unknown constraint on the matter that absorbs or emits the radiation.

The effects of electromagnetic radiation upon living cells, including those in humans, depends upon the radiation's power and frequency.

The problem had been stated by Kirchhoff in 1859: "how does the intensity of the electromagnetic radiation emitted by a black body (a perfect absorber, also known as a cavity radiator) depend on the frequency of the radiation (i.

Thermal radiation is generated when energy from the movement of charged particles within atoms is converted to electromagnetic radiation.
