Motion Detect
Explain how astronomers use the doppler effect to detect the motion of other galaxies?
Certain spectral frequencies are always emitted or absorbed at a constant wavelength and appear as lines in the spectrum. They can be identified by their position relative to other lines. The doppler effect causes a shift in the wavelength of these lines. From the amount of shift we can infer the galactic velocity toward or away from us.
