The correct answer is:
**Light can travel in the air or a vacuum and the speed is constant whether the light source is stationary or moving.**
Light travels at a constant speed of approximately 299,792 kilometers per second (or about 186,282 miles per second) in a vacuum, and while its speed can be affected by different media (like water or glass), this speed remains constant regardless of the motion of the light source, according to the principles of relativity.
