Answer:
B. Redshifts occur when the light source and observer move farther apart, and the light observed shifts to a longer wavelength.
Explanation:
Redshift is a phenomenon where electromagnetic radiation from an object undergoes an increase in wavelength such that the light seems to be shifted towards the red part of the spectrum. Â Redshifts are used to track the rotation of our galaxy by the astronomers. Redshifts occur when the light source and observer move farther apart, and the light observed shifts to a longer wavelength.
