The refractive index of ionosphere is
- A zero
- B more than one
- C less than one
- D 1 (one)
Answer & Solution
Correct Answer
(C) less than one
Step-by-step Solution
Detailed explanation
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.
