Is the Speed of Light Really 3000 km/s?

AI Thread Summary
The speed of light is approximately 299,792 kilometers per second, not 3000 km/s as initially stated. The original claim is incorrect by a factor of 100. This speed is measured in a vacuum, and light travels slower in other media. Accurate understanding of the speed of light is crucial in physics. The correct value is 299,792 km/s.

Well, it's 299 792 458##\text{ms}^{-1}##, or, equivalently 299 792,458##\text{kms}^{-1}##.

You dropped a couple of zeroes. And this is the speed in a vacuum; it is slower in other media.
 
You are off by a factor of 100.
It is 299,792 Km/s
