Generation

The Doppler shift occurs when a light source moves relative to an observer, causing the wavelengths of light in its spectrum to stretch or compress. When an object moves away from you, its spectral lines shift toward longer (redder) wavelengths—called redshift—while an object moving toward you shows spectral lines shifted toward shorter (bluer) wavelengths—called blueshift. The amount of shift is directly proportional to the object's velocity along your line of sight, which is why astronomers use it to measure how fast stars and galaxies are moving toward or away from Earth. This is the same effect you hear with sound when an ambulance siren changes pitch as it passes you, but applied to light waves.
