Redshift, displacement of the spectrum of an astronomical object toward longer (red) wavelengths. It is attributed to the Doppler effect, a change in wavelength that results when an object and an observer are in motion with respect to each other. Learn a
A redshift is a shift in the frequency of an electromagnetic wave caused by an object’s motion. Light from objects moving away from an observer have their light waves shifted toward the red part of the spectrum. Redshift is commonly observed inastronomy, particularly in the observation of ve...
