Redshift, blueshift and the Doppler effect 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...
We believe that the redshift and blueshift are not entirely due to the Doppler's Effect, but also due (as in the light bending) to the medium composition (medium that could be formed by waves, particles, plasma, dust, gaseous, fluids, solids, etc.), to the medium density, to the ...
in the lines of the spectrum of an astronomical object towards a longer wavelength (the red end of an optical spectrum), relative to the wavelength of these lines in the terrestrial spectrum, usually as a result of theDoppler effectcaused by the recession of the object. Compare:blueshift ...
When the Doppler effect causes the shift, the object approaches (blueshift) or recedes (redshift) from the observer. We would observe a blueshift if the universe is shrinking and a redshift if the universe is expanding. When a gravitational effect causes the shift, the light is emitted from...

Straightforward calculation of the observable spectrum from a canonical ensemble of monochromatic radiators yields an overall blueshift rather than a redshift. It is concluded that the customary explanation of the thermal redshift as a second-order Doppler effect does not bear closer examination, and ...
