(electromagnetic) radiation
101radiation pattern — noun graphical representation (in polar or Cartesian coordinates) of the spatial distribution of radiation from an antenna as a function of angle • Syn: ↑radiation diagram, ↑pattern • Hypernyms: ↑graph, ↑graphical record • Part Meronyms: ↑lobe …
102radiation — 1. Transfer of heat through electromagnetic waves from hot to cold. 2. Electromagnetic waves of energy having frequency and wavelength. The shorter wavelengths (higher frequency) are more energetic. The electromagnetic spectrum is comprised …
103Planck radiation — Electromagnetic radiation which is in the state of thermal equilibrium at some temperature T. Quantum statistics of bosons results in spectrum of distribution of energy to be described by Planck s black body radiation formula …
10421-centimetre radiation — electromagnetic radiation of radio wavelength emitted by cold, neutral, interstellar hydrogen atoms. The hydrogen atom is composed of a positively charged particle, the proton, and a negatively charged particle, the electron. These… …
105Infrared Radiation — Electromagnetic radiation whose wavelengths lie in the range from 0.75 micrometer to 1000 micrometers; invisible long wavelength radiation (heat) capable of producing a thermal or photovoltaic effect, though less effective than visible light …
