The Doppler Effect
... Absorption lines correspond to the elements that make up a star. Every element gives its own absorption signature to the star’s light. If we know what a star is made of, we can usually predict where the absorption lines should be in the star’s spectrum of light. ...

Einstein Postulates for Special Relativity
... A light source travels with velocity v past a detector at D. The special theory of relativity predicts a transverse Doppler effect as the source passes through point P, where the direction of travel is perpendicular to the line extending through D. Classical theory predicts no such effect. ...
