AnswerThe speed of light, traveling in the vacuum, it's not going to change if the light source moves.ExplanationLight is in the list of the electromagnetic spectrum. Electromagnetic waves do not need a material medium for its propagation. This means that you can travel in the vacuum and so is the light. The speed of light is always constant and does not depend on the source. So the correct statement about the light; the speed of light, traveling in the vacuum, it's not going to change if the light source moves.
