Principle of constant light speed

The speed of light in a vacuum is the same for any observer. The principle of constant speed of light, in the special theory of relativity, refers to no matter what inertial system (inertial reference system) is observed, the speed of light propagation in vacuum is a constant, and does not follow the relative movement of the light source and the observer's reference system And change. This value is 299,792,458 meters / second.
