on. What speed would an observer on Earth measure for the light from the
spotlight?
A. 0.5 x 108 m/s
B. 2.5 x 108 m/s
O C. 5.5 x 108 m/s

Answer 2

Light :

Explanation:

• Light travels in space at a speed of 3.0 x $10^8$ m/s.

• A space probe is traveling toward the Earth at a speed of 2.5 x $10^8$ m/s.

• When one of its spotlights is turned on it should be travel through space & then it reaches the sight of the observer.  

• The speeds with which it reaches the Earth are equal to the speed of light in space.

• 3.0 x $\mathbf {10^8}$ m/s would an observer on the Earth measure for the light from the spotlight.
