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 738nm, 781.2nm, 874.8nm, and 1180.8nm respectively. At what wavelength would you make observations in order to detect its Lyman line of hydrogen for this distant galaxy, which has a laboratory or rest wavelength of 121.6 nm
