Motion of a light source, like stars in distant galaxies, causes the spectral lines to shift positions as well. an object's motion causes a wavelength shift δλ = λnew - λres. the amount of shift in the spectral lines can tell astronomers how galaxies are moving relative to our position on earth. the wavelength shift depends on
