In which does light travel the fastest
WebExplain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water. How does light travel that fast? Ergo, light is made of electromagnetic waves and it travels at that speed, because that is exactly how quickly waves of electricity and magnetism travel through space.Jul 16, 2024 WebThe speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, the speed of light is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could circle the Earth 7.5 times in one second.
