Light travels through space at a speed of 3.0 × 108 m/s. A space probe is traveling at 2.5 × 108 m/s when one of its spotlights is turned on. What speed would an observer on Earth measure for the light from the spotlight? A.
3.0 × 108 m/s

B.
5.5 × 108 m/s

C.
0.5 × 108 m/s

D.
The speed would depend on whether the probe is moving toward or away from Earth.
