The loss of light when it passes through air or dust
  • noun

translation icon : extinción
  • Extinction refers to the ability of the screen to maintain polarization.
  • light extinction
  • extinction coefficient

The electron plasma has a large extinction coefficient, which means it absorbs light strongly.

Examples

  • The most interesting information has come from radio observations, which suffer almost no extinction.

    Academic text (1992)
  • Her research interests include dwarf galaxies, star formation, and the extinction of starlight due to dust in different types of galaxies.

    Academic text (1993)
  • Equation 2 is referred to as the extinction profile.

    Academic text (2018)
  • A good screen is a screen that shows high brightness and high extinction.

    Academic text (2003)
  • For nearby sources, the extinction is small enough that most light can propagate unaffected.

    Academic text (1999)
  • The electron plasma has a large extinction coefficient, which means it absorbs light strongly.

  • Extinction is the combination of true absorption of light and scattering.

    Academic text (1999)
  • The presence of dust, haze, or excess water vapor will increase the extinction, k, well above 0.3 magnitudes to a higher level.

    Academic text (2004)
  • The high extinction of light through dense fog makes it difficult to see the road ahead.

  • As the sun sets, the extinction of its rays through the atmosphere creates a beautiful orange hue.

Morphology

extinction = extinct (opaque) = ex + tinct + ion

The scientific meaning related to radiation is not directly derived from the base word 'extinct'.

Etymology

Extinction comes from the same Latin root as extinguish, with ex- meaning 'out' and stinguere meaning 'to put out'. In science, extinction of light or radiation means the light is being 'put out' or lost as it passes through air, dust, or other material.
