Question

The refractive index of the atmosphere is _____ related to its refractive index.

  1. Directly
  2. Indirectly
  3. Inversely
  4. Not 

hintHint:

The refractive index of air or the refractive index of the atmosphere is approximately 1.002

The correct answer is: Inversely


    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 refractive index of the atmosphere is __Directly___ related to its refractive index.
