An astronomer observes electromagnetic waves emitted by oxygenatoms in a distant galaxy that have a frequency of 5.710x10^14 Hz. In the laboratory on earth, oxygen atoms emit waves that have afrequency of 5.841x10^14 Hz. Determine the relative velocity of the galaxy with respect to the astronomer on the earth. Note: The speedof light is 2.9979x10^8 m/s.
