The speed of electromagnetic waves in vacuum, often denoted as "c," is approximately 299,792,458 meters per second (or about 300,000 kilometers per second). This speed is often rounded to 3×10^8 meters per second for convenience.
This speed is a fundamental constant of nature and is the same for all types of electromagnetic waves, including visible light, radio waves, microwaves, X-rays, and more. It's a universal speed limit that is the maximum speed at which information or energy can be transmitted through the vacuum of space.
