What is the value of the speed of light in meters per second?

The speed of light in a vacuum is a fundamental constant in physics, universally recognized as approximately 299,792,458 meters per second. For practical purposes, this value is often rounded to 3.00 x 10^8 m/s. This speed is significant for many areas of physics, including electromagnetism and relativity, and plays a crucial role in the equations governing these fields.

Knowing this value is essential because it serves as the upper limit for the speed at which information and matter can travel in the universe. Other options presented do not accurately reflect the established scientific consensus regarding the speed of light, emphasizing the importance of familiarity with such fundamental constants in scientific discourse.
