Question:
The refractive index of ionosphere is
The refractive index of ionosphere is
Show Hint
In regions like the ionosphere, the refractive index can be less than 1 due to high electron density.
Updated On: May 13, 2025
- zero
- more than one
- less than one
- 1 (one)
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The ionosphere is a plasma where electromagnetic waves travel faster than in vacuum under certain conditions. This causes the refractive index to be less than 1.
