Light waves of the Doppler effect Are volatile, the light will also appear this effect, it is called the Doppler - Fizeau effect. Because the French physicist Fizeau (1819 ~ 1896) in 1848 independently from the wavelength of the star partial Move an explanation, pointing out that this effect is measured using the relative velocity approaches the star. The difference between light waves and sound waves is that light waves change in frequency of people feeling that it was the color change. if the star away from us away, then the light The spectrum to the red light on the direction of movement, known as the red shift; if the star towards our movement, light purple lines on the move, known as the blue shift.
