The K-correction must be applied to observations of extragalactic objects to account for this phenomenon.
The K-correction must be applied to observations of extragalactic objects to account for this phenomenon. In principle, its value can be plotted against the apparent magnitudes of objects with the same intrinsic luminosity to yield a value for the deceleration parameter. One version of this phenomenon, together with time dilation, is seen in the Sachs-Wolfe effect. That version, predicted by general relativity, occurs when photons climb out of gravitational potential wells. FTP, transverse relative motion must, according to the relativistic Doppler shift, produce this increase in the wavelength of light.
