In order to calculate the redshift, one has to know the wavelength of the emitted light in the rest frame of the source: in other words, the wavelength that would be measured by an observer located adjacent to and comoving with the source. Meer weergeven In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength … Meer weergeven The spectrum of light that comes from a source (see idealized spectrum illustration top-right) can be measured. To determine the redshift, one searches for features in the … Meer weergeven The redshift observed in astronomy can be measured because the emission and absorption spectra for atoms are distinctive and well … Meer weergeven The opposite of a redshift is a blueshift.
