Red shift doppler effect, animation

Référence de la vidéo 12081260
Red shift doppler effect. Animation of a star emitting light waves that are closer together in the direction of its travel (blue-shifted), and further apart in the opposite direction (red-shifted). This causes the observed colour of light to be a higher frequency (blue) as it approaches, and a lower frequency (red) as it recedes. This shift is known as the Doppler effect, after Austrian physicist Christian Doppler (1803-1853). The Doppler effect is also observed in other examples, such as water waves and sound waves.
