Question

Quizplus · Accepted Answer

Light travels fastest in a vacuum, as it is not hindered by any medium or particles. It has a speed of approximately 299,792,458 meters per second in a vacuum, which is the maximum speed at which anything can travel in the universe. In comparison, light travels slower in air and other materials due to scattering and absorption by molecules, which reduces its speed.
