In the check your learning section of example 27.1, you were told that several lines of hydrogen absorption in the visible spectrum have rest wavelengths of 410 nm, 434 nm, 486 nm, and 656 nm. in a spectrum of a distant galaxy, these same lines are observed to have wavelengths of 492 nm, 521 nm, 583 nm, and 787 nm, respectively. the example demonstrated that z = 0.20 for the 410 nm line. show that you will obtain the same redshift regardless of which absorption line you measure.
