●对于电磁波●红移 - 当光从观察者移开时,明显的频率会降低,增加波长,从而将光转向频谱的可见光部分红色。●蓝移 - 当光向观察者移动时,表观频率会增加,减小波长,从而将光向蓝色移动。● When a source of light and an observer are moving relative to each other, the observed wavelength of light differs from the actual wavelength of light ● When a light wave is emitted by a source fixed in the moving inertial frame S', the observer in S sees the wavelength measured in S' to be shorter by a factor of sqrt(1 - v 2 / c 2 ) ● Because the observer sees the source moving away within s,在S中到达观察者的波模式也由因子1 + V / c伸展。●组合效应由:< / div>给出:< / div>
