Emission

Emission may refer to:

  • Flue gas, also:
    • Exhaust gas, flue gas occurring as a result of the combustion of a fuel
  • Emission of air pollutants
  • Emission of greenhouse gases, a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range
  • Emission (electromagnetic radiation), the process by which the energy of a photon is released by another entity
  • Emission (radiocommunications), the radio signal (usually modulated) emitted from a radio transmitter
  • Emission coefficient, a coefficient in the power output per unit time of an electromagnetic source
  • Emission factor
  • Emission line, or "spectral line", a dark or bright line in an otherwise uniform and continuous spectrum
  • Emission nebula, a cloud of ionized gas emitting light of various colors
  • Emission spectroscopy, photoemission spectroscopy, flame emission spectroscopy and other types of spectroscopy
  • Emission standard, requirements that set specific limits to the amount of pollutants that can be released into the environment
  • Emission theory, a competing theory for the special theory of relativity, explaining the results of the Michelson-Morley experiment
  • Emission theory (vision), the proposal that visual perception is accomplished by rays of light emitted by the eyes
  • Emissions trading, a market-based approach used to control pollution by providing economic incentives for achieving reductions in the emissions of pollutants
  • Ejaculation, the ejecting of semen from the penis; also, specifically:
    • Nocturnal emission, ejaculation experienced during sleep
  • Light emission
  • Thermionic emission, the flow of charged particles called thermions from a charged metal or a charged metal oxide surface, archaically known as the Edison effect
  • Noise emission; see Noise
  • Exhalation, especially where the velocity of exhaled air can influence the harmonic generating properties of a vibrating body, such as the reed of a musical instrument like the saxophone

Famous quotes containing the word emission:

    Approximately 80% of our air pollution stems from hydrocarbons released by vegetation, so let’s not go overboard in setting and enforcing tough emission standards from man-made sources.
    Ronald Reagan (b. 1911)
