The refractive index of ionosphere is

Options

  1. Azero
  2. Bmore than one
  3. Cless than one
  4. D1 (one)

Correct answer

C. less than one

Step-by-step solution

Ionospere is the topmost layer of earth atmosphere whose density is much smaller than the density of lower layers of earth's atomosphere. Therefore, refractive index ionospher is less than one.
