Question

Answer 1

Answer:

Explanation:

Light in air is 1.0003 times slower than light in a vacuum, which slows it all the way down from 299,792,458 meters per second to 299,702,547 meters per second. ... But if you're in a vacuum, the index of refraction is precisely 1; there is no change to the speed of light in a vacuum

hope it helps u and please mark as brainliest

Answer 2

No, but it is taken to be the same.

Speed in vacuum=299792465 kmph

Speed in air=299792450(~) kmon

since difference is neglible, it is taken to be the same

hope this helps you
