And I noticed that the waves of sound were under a slight Doppler effect.
Recent spectroscopic observations of the nebul applying the principle of Doppler have revealed high velocities of rotation.Astronomy
Neither does it cause any change of colour or Doppler effect; that is, no shift of lines in spectrum.The Ether of Space
Angle, strength and Doppler movement were computed to find course and distance.Planet of the Damned
The method of detecting binary stars by means of the spectroscope is an application of Doppler's principle.Astronomy of To-day

Word Origin and History for doppler
1871, in reference to Christian Doppler (1803-1853), Austrian scientist, who in 1842 explained the effect of relative motion on waves (originally to explain color changes in binary stars); proved by musicians performing on a moving train. Doppler shift is the change of frequency resulting from the Doppler effect.
- Austrian physicist and astronomer who in 1842 explained the effect, now named for him, of variations in the frequency of waves as a result of the relative motion of the wave source with respect to the observer.
