The speed of light in a vacuum is 186,000 miles per second. ... The round-trip speed of light in a vacuum is 186,000 miles per second. It is impossible to measure the one-way speed of light. For all we know, it could be instantaneous.

Is speed of light different in different directions?
Light does not travel at the same speed in all directions under the effect of an electromagnetic field. ... In an absolute vacuum, light travels at a constant velocity of 299,792,458 m/s. It seems natural that it should propagate at the same speed in all directions.
What does instantaneous mean in lighting?
2 a particular moment or point in time. at the same instant.
Why is the speed of light not instantaneous?
This speed, which we call "c," is measured to be 300,000,000 meters per second. ... That something, the universal conversion factor, is the speed of light. The reason that it is limited is simply the fact that a finite amount of space is equivalent to a finite amount of time.
