In this worksheet, we will practice calculating the radial velocity of a star or galaxy using the amount by which absorption lines in the spectrum of light from it are shifted. The diagram shows the spectral lines in the light from two galaxies, as well as the same spectral lines in the light from a laboratory source. sharkproject.org
