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 websiteThe Physics Classroom. The Doppler Effect w...
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 ...
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...
Which moves faster redshift or blueshift? Thus, the Doppler effect for light is called a 'blueshift' if the light source is coming toward an observer, and a 'redshift' if it is moving away.The faster the object moves, the greater the blueshift or redshift." Why do galaxies appear red?

If the object comes closer, the shift is towards blue, and we then speak of "blueshift". In other words, the farther away the object is, the higher its redshift (z). This phenomenon is explained by the Doppler effect. The Doppler effect is a modification of the frequency of a wave...

frequency distribution would change, and the peak wavelength would shift after traveling through space. Whether the peak shifts to the red (redshift) or to the blue (blueshift) depends on the optical characteristics of the space medium, and it can be determined only ...
