A red shift in the spectrum of the light from an object indicates the object is moving a. away from you. A redshift occurs when light waves are stretched into lower frequencies. a.away from

Answer 2

A red shift in the spectrum of the light from an object indicates the object is moving a. away from you. A redshift occurs when light waves are stretched into lower frequencies. This is an example of the Doppler effect which makes use of the visible light spectrum where blue light has the highest frequency and red light has the lowest. This concept is often used by astronomers to measure the distances of galaxies and stars.
