Explanation of red shift
WebThe precise definition of the red shift is the increase in the wavelength divided by the original wavelength; for a given relative velocity, this quantity is the same for all wavelengths or colors. For example, a red shift of 0.05 means that all wavelengths are increased by 5% because of the recessional velocity. WebLight coming from a compact massive object should be slightly redshifted; that is, the light should have a longer wavelength. Measuring this was a delicate business, as the expected shift was small and could easily be masked by other …
