blue shift

blueshift,

in astronomy, the systematic displacement of individual lines in the spectrumspectrum,
arrangement or display of light or other form of radiation separated according to wavelength, frequency, energy, or some other property. Beams of charged particles can be separated into a spectrum according to mass in a mass spectrometer (see mass spectrograph).

The amount of displacement is a function of the object's relative velocity toward the observer. Most observed blue shifts are the result of the Doppler effectDoppler effect,

blue shift

[′blü ‚shift] (astronomy) A displacement of lines in the spectrum of a celestial object toward shorter wavelengths, indicating motion of the object toward the observer.

单词	blue shift
释义	blue shift blue shift n. A decrease in the wavelength of radiation emitted by an approaching celestial body as a consequence of the Doppler effect. [From the fact that the shorter wavelengths of light are at the blue end of the visible spectrum.] blue shift A decrease in the wavelength of radiation emitted by an approaching celestial body as a result of the Doppler effect. Objects appear bluish because the shorter wavelengths of light are at the blue end of the visible spectrum. Compare red shift.
