What is the speed of light?
The speed of light is a fundamental physical constant, denoted by the letter c. It is the speed at which electromagnetic radiation (such as light) propagates in a vacuum. The value of the speed of light in a vacuum is exactly 299,792,458 meters per second (or about 670,616,629 miles per hour).
The speed of light is an important quantity in many areas of physics, including relativity, electromagnetism, and quantum mechanics. It is also used in everyday life, such as in the fields of telecommunications and astronomy. The constancy of the speed of light is a key principle of the theory of relativity, which postulates that the laws of physics are the same for all observers in all inertial reference frames.
