The speed of light in a vacuum is approximately 3.00 x 108 meters per second. This means that light travels at a speed of about 300 million meters in just one second.
To put it in perspective, this speed is incredibly fast. Light can travel from the Sun to Earth in about 8 minutes and 20 seconds, covering a distance of about 93 million miles (or 150 million kilometers).
Using scientific notation helps to represent such large numbers more manageably and clearly. In this case, 3.00 x 108 is a concise way to express the speed without writing out all the zeros, making it easier to work with in scientific calculations and discussions.
