Question

Quizplus · Accepted Answer

Light does not encounter any particles to slow it down in a vacuum, so it travels at its maximum speed of approximately 299,792,458 meters per second. In contrast, light slows down when passing through materials such as air, glass, or water, so it will travel slower in warm or cool air compared to a vacuum.
