“Doppler shift”的概念、定义、翻译、参考文献-科学参考

Doppler shift

Astronomy

The change in wavelength of electromagnetic radiation as a result of relative movement between the source and the observer. If the source is moving towards the observer, the wavelengths become shorter and the spectral lines are shifted towards the blue end of the spectrum (a blueshift). If the source is receding, the wavelengths become longer and spectral lines are moved towards the red end of the spectrum (a redshift). The effect is named after C. J. Doppler.

Geology and Earth Sciences

The apparent change in frequency of waves whose source is moving towards or away from an observer. It was first described by the Austrian physicist Christian Doppler (1803–53).
