disperse system


noun

  1. Also dispersal. an act, state, or instance of dispersing or of being dispersed.
  2. Optics.
    1. the variation of the index of refraction of a transparent substance, as glass, with the wavelength of light, with the index of refraction increasing as the wavelength decreases.
    2. the separation of white or compound light into its respective colors, as in the formation of a spectrum by a prism.
  3. Statistics. the scattering of values of a variable around the mean or median of a distribution.
  4. Military. a scattered pattern of hits of bombs dropped under identical conditions or of shots fired from the same gun with the same firing data.
  5. Also called disperse system. Physical Chemistry. a system of dispersed particles suspended in a solid, liquid, or gas.
  6. (initial capital letter) Diaspora(def 1).

    1. the separation of electromagnetic radiation into constituents of different wavelengths
    2. a measure of the ability of a substance to separate by refraction, expressed by the first differential of the refractive index with respect to wavelength at a given value of wavelengthSymbol: D
  3. statistics the degree to which values of a frequency distribution are scattered around some central point, usually the arithmetic mean or median
  4. chem a system containing particles dispersed in a solid, liquid, or gas
  5. military the pattern of fire from a weapon system
    1. the range of speeds of such objects as the stars in a galaxy
    2. the frequency-dependent retardation of radio waves as they pass through the interstellar medium
    3. the deviation of a rocket from its prescribed path
  6. ecology the distribution pattern of an animal or a plant population

noun

  1. the Dispersion another name for the Diaspora
n.

late 14c., from Old French dispersion (13c.), from Latin dispersionem (nominative dispersio) “a scattering,” noun of action from past participle stem of dispergere (see disperse).

n.

  1. A system, such as a colloid, consisting of a substance dispersed in a medium.

n.

  1. The act or process of dispersing.
  2. The state of being dispersed.
  3. Disperse system.

  1. The separation by refraction of light or other radiation into individual components of different wavelengths. Dispersion results in most materials because a material’s index of refraction depends on the wavelength of the radiation passing through it; thus different wavelengths entering a material along the same path will fan out into different paths within it. Prisms, for example, diffuse white light (which contains an even mixture of visible wavelengths) into its variously colored components; rainbows are an effect of dispersion in water droplets.
