How is redshift measured

WebStarChild Question of the Month for November 2001 Question: How do we measure the distances to things in space? Answer: It is not an easy thing to measure the distances to objects in the universe since these objects are usually very far away. We can't just run out there with a ruler! Similar measurements have been performed on other galaxies, such as Andromeda. As a diagnostic tool, redshift measurements are one of the most important spectroscopic measurements made in astronomy. Extragalactic observations. The most distant objects exhibit larger redshifts corresponding … 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 spectrum such as absorption lines, emission lines, or other variations in light intensity. If … 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. A blueshift is any decrease in wavelength (increase in energy), with a corresponding increase in … Meer weergeven The history of the subject began with the development in the 19th century of classical wave mechanics and the exploration … Meer weergeven 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 … Meer weergeven The interactions and phenomena summarized in the subjects of radiative transfer and physical optics can result in shifts in the wavelength and frequency of electromagnetic … Meer weergeven
