Question

Quizplus · Accepted Answer

According to the theory of relativity, the speed of light in a vacuum is constant and independent of the motion of the observer or the source. Therefore, the laser will also be traveling at the speed of light from the perspective of the observer, regardless of the spaceship's velocity. Thus, the correct answer is B, the speed of light.
