An astronomer observes electromagnetic waves emitted by oxygen atoms in a distant galaxy that have a frequency of 5.710 × 1014 Hz. In the laboratory on earth, oxygen atoms emit waves that have a frequency of 5.841 × 1014 Hz. Determine the relative velocity of the galaxy with respect to the astronomer on the earth. Note: The speed of light is 2.9979 × 108 m/s.
