Answer 2

The speed of light in a vacuum is 3×109 m s−1

Explanation:

The speed of light in a medium is slower than speed of vacuum and is mostly determined by the axis of the beam. (differs case to case).

The rate at which an object moves or operates is termed as Speed. The fastest thing on earth is the light. Things which do not have any weight or mass can move very fast. After light, the next fastest thing on earth is the shadow.
