| Doppler effect |
The effect by which motion changes a wave's perceived frequency. If the wave's source and receiver are moving closer, the perceived frequency will be higher. As source and receiver move apart, the perceived frequency decreases.

| Doppler shift |
occurs when sound is generated by, or reflected off of, a moving object. By measuring the star's spectrum and comparing it to the spectrum of a standard lamp, then the amount of the Doppler shift can be measured. The amount of the Doppler shift tells us how fast the star is moving relative to us. In addition, the direction of the Doppler shift can tell us the direction of the star's movement. ...
