WebWhat is redshift? The apparent movement of spectral lines toward the red end of the spectrum. Why do we get a redshift? Observed wavelength is increase What galaxies … WebIf the redshift is z, then the wavelength of light you observe is at a wavelength that is 1 + z times longer than the wavelength emitted in the frame of reference of the galaxy. In this case z = 0.373, so when you observe light centered on say the 3.4 micron band, then the light was emitted at a wavelength of 3.4/1.373 microns.
