I have a problem that I cannot get the correct answer.
An Astronomer observes electromagnetic waves emmitted by oxygen atoms in a distant galaxy that have a frequency of 5.71 *10^14 Hz. On earth, oxygen atoms emit waves that have a freq. of 5.841 *10^14. What is the relative velocity of the galaxy with respect to the astronomer on earth.
Vrel = [(F(observed) - F(Source))/(2*F(Source))] * c
Vrel = [(5.710*10^14 - 5.841*10^14)/(2*5.841*10^14)] * (3.00 *10^8)
answer = 3.3641 *10^6 m/s
What is wrong with my calculations?
The correct answer is 6.724 * 10^6 m/s
Thanks
