Differing magnitudes of this effect explains why K corrections are necessary to convert apparent magnitudes to absolute magnitudes.
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 which a light source moving away from an observer appears to increase in wavelength toward a namesake color.
