ELECTROMAGNETIC RADIATION
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
Radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge
Synonyms:
electromagnetic radiation; electromagnetic wave; nonparticulate radiation
Classified under:
Nouns denoting natural phenomena
Hypernyms ("electromagnetic radiation" is a kind of...):
radiation (energy that is radiated or transmitted in the form of rays or waves or particles)
Meronyms (parts of "electromagnetic radiation"):
photon (a quantum of electromagnetic radiation; an elementary particle that is its own antiparticle)
Hyponyms (each of the following is a kind of "electromagnetic radiation"):
actinic radiation; actinic ray (electromagnetic radiation that can produce photochemical reactions)
beam; electron beam; ray (a group of nearly parallel lines of electromagnetic radiation)
black-body radiation; blackbody radiation (the electromagnetic radiation that would be radiated from an ideal black body; the distribution of energy in the radiated spectrum of a black body depends only on temperature and is determined by Planck's radiation law)
gamma radiation; gamma ray (electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength)
line (a single frequency (or very narrow band) of radiation in a spectrum)
microwave (a short electromagnetic wave (longer than infrared but shorter than radio waves); used for radar and microwave ovens and for transmitting telephone, facsimile, video and data)
radio emission; radio radiation; radio wave (an electromagnetic wave with a wavelength between 0.5 cm to 30,000 m)
roentgen ray; X-radiation; X-ray; X ray (electromagnetic radiation of short wavelength produced when high-speed electrons strike a solid target)
Context examples:
A single unit of electromagnetic radiation, generally considered to be a discrete particle having no mass or charge.
(Photon, NCI Thesaurus)
Electromagnetic radiation between the ultrahigh frequency radio and infrared (in the 10e-3 (micro) to about 0.5 X 10e-1 meter) region of the spectrum.
(Microwave Radiation, NCI Thesaurus)
A spectrometer that applies some form of energy to a substance, thereby causing emission of electromagnetic radiation which is then quantified using a detector.
(Emission Spectrometer, NCI Thesaurus)
A group of nearly parallel rays of electromagnetic radiation or a stream of particles.
(Beam, NCI Thesaurus)
It is also believed that the early moon had a magnetosphere - a magnetic field which would have deflected the sun's deadly electromagnetic radiation - similar to Earth's.
(Life Could Exist on Moon 4 Billion Years Ago, The Titi Tudorancea Bulletin)
A method in which electromagnetic radiation, in the form of light emission, is generated from an electrochemical reaction in a solution.
(Electrochemiluminescence, NCI Thesaurus)
A method in which electromagnetic radiation, in the form of light emission, is generated from an electrochemical reaction in a solution due to the formation of antigen-antibody complexes.
(Electrochemiluminescence Immunoassay, NCI Thesaurus)
An area of electric and magnetic forces caused by electromagnetic radiation.
(Electromagnetic field, NCI Dictionary)
RFI is a disturbance that affects an electrical circuit due to either electromagnetic conduction or electromagnetic radiation emitted from an external source.
(Device Radiofrequency Interference Evaluation Result, Food and Drug Administration)
Testing the device to detect device malfunctions caused by a disturbance affecting an electrical circuit due to electromagnetic radiation emitted from an external source.
