Question

Refractive Index of a different levels of Earth's atmosphere changes continuously​

Answer 1

Refractive index of different levels of Earth's atmosphere changes continuously because as we go above the air becomes rarer and rarer and hence the difference between the densities is experienced .

Answer 2

Answer:

Explanation:

This is because at different altitudes the atmosphere has different densities of air. Since refractive index depends on density of the medium, refractive index of atmosphere is different at different altitudes.
