Consider a spiral galaxy that is moving directly away from Earth
with a speed V = 2.56 × 105 at its center. The galaxy is
also rotating about its center, such that points in its spiral arms
are moving with a speed v = 7.35 × 105 m/s relative to
the center. If light with a frequency of 7.408 × 1014 Hz
is emitted in both arms of the galaxy, what frequency is detected
by astronomers observing the arm that is moving away from
Earth?
