Answer:
Redshift increases with distance
Step-by-step explanation:
Edwin Hubble discovered a relation for distance and radial velocities of galactic nebulae from their redshifts i.e., when an object is moving away from earth the wavelength of light gets changed due to the Doppler effect.
He also found that two galaxies when further apart have a greater speed by which they are moving away from each other. This was used to prove the Big Bang theory laid down by Georges Lemaître.
