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 and simultaneous increase in frequency and energy, is known as a negative redshift, or blueshift. The terms derive from the colours red and blue which form the extremes of the v… WebThe star labeled A and its A absorption lines behave in the same manner, shifting to the blue when moving toward the observer and shifting to the red when moving away.

Doppler Shift - University of California, Los Angeles
WebBlue shifts corresponding to the absorption edge in the UV-A (310–400 nm) range are obtained from ultraviolet (UV) absorption spectra. The absorption edge red shift is … The concept of redshift and blueshift is closely related to the Doppler effect — which is an apparent shift in soundwave frequency for observers depending on whether the source is approaching or moving away from them, according to the educational website The Physics Classroom(opens in new tab). The … See more At least three types of redshift occur in the universe — from the universe's expansion, from the movement of galaxies relative to each other and from "gravitational redshift," which … See more Redshift helps astronomers compare the distances of faraway objects. In 2011, scientists announced they had seen the farthest object ever seen— a gamma-ray burst called GRB 090429B, which emanated from an … See more Learn more(opens in new tab) about the Doppler Effect with NASA and explore Doppler Shift with the University of California, Los Angeles(opens in new tab).
