Question
The refractive index of the atmosphere is _____.
- Constant everywhere
- Different in different places
- Is equal to 1 everywhere
- Is equal to 0 everywhere
Hint:
The refractive index of air or the refractive index of the atmosphere is approximately 1.002 which implies that the speed of light in air is 1.002 times slower than that in a vacuum.
The correct answer is: Different in different places
The refractive index of air or the refractive index of the atmosphere is approximately 1.002 which implies that the speed of light in air is 1.002 times slower than that in a vacuum.
