the doppler shift

after C.J. Doppler (1803-1853)

Doppler shift is a shift of characteristics of a frequency spectrum (such as spectral lines) because of the doppler effect. A doppler speed can be calculated from a doppler shift. A doppler shift of light to smaller frequencies is called redshift, and a doppler shift to greater frequencies blueshift.
