A gravitational redshift can also equivalently be interpreted as gravitational time dilation at the source of the radiation: if two oscillators (attached to transmitters producing electromagnetic radiation) are operating at different gravitational potentials, the oscillator at the higher gravitational potential …

WebIn special relativity, redshift is related to radial velocity vby 1 + z= v u u t1 + v=c 1 v=c (9) where cis the speed of light. In general relativity, (9) is true in one particular coordinate system, but not any of the traditionally used coordinate systems. WebFirst, rearrange the terms of the Hubble relation to calculate distance as d = v / H 0. Then rearrange the terms of the redshift equation to get v = z c. Combining the two results …

In general relativity one can derive several important special-case formulae for redshift in certain special spacetime geometries, as summarized in the following table. In all cases the magnitude of the shift (the value of z) is independent of the wavelength. If a source of the light is moving away from an observer, then redshift (z > 0) o…
