electromagnetic wave

Noun
  1. Radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge (synset 111471253)
    is a type of: radiation - energy that is radiated or transmitted in the form of rays or waves or particles
    subtypes:
    • 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 ray, x-radiation, x-ray - electromagnetic radiation of short wavelength produced when high-speed electrons strike a solid target
    has: photon - a quantum of electromagnetic radiation; an elementary particle that is its own antiparticle
    same as: electromagnetic radiation, nonparticulate radiation
