Differing magnitudes of this effect explains why K corrections are necessary to convert apparent magnitudes to absolute magnitudes. The last scattering surface has the maximum value of 1100 for a parameter describing this effect, which roughly equals a ratio of two scale factors, minus one. In a 1959 experiment, the relativistic contribution to this effect was cancelled out by placing an iron-57 sample inside a loudspeaker on top of a building. A quantity symbolized  z  named for this effect is a proxy for (*) astronomical distances: that's because Hubble's law predicts most objects display this effect since the universe is expanding. For 10 points, name this result of the Doppler effect, in

For 10 points, name this result of the Doppler effect, in which a light source moving away from an observer appears to increase in wavelength toward a namesake color.
