Most of the galaxies in the universe are observed to be moving away from Earth. Suppose a particular galaxy emits orange light with a frequency of 5.000 \times 10^{14} {\rm Hz}. If the galaxy is receding from Earth with a speed of 3725{\rm km/s} , what is the frequency of the light when it reaches Earth?
