Problem 4 Earth V Consider a spiral galaxy that is moving directly away from Earth with a speed V=2.56 × 10³ 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 x 105 m/s relative to the center. If light with a frequency of 7.408 x 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? This is a problem about Doppler Effect. You just need to figure out the signs.
