The maximum frequency of transmitted radio waves above which the radio waves are no longer reflected back by ionosphere is ______ ( N = maximum electron density of ionosphere, g = acceleration due to gravity)
Options
- Ag N
- Bg N 2
- Cg N
- Dg 2 N 2
Correct answer
C. g N
Step-by-step solution
For ionosphere, the maximum frequency of radius waves that can be reflected back is given by g N . Where N is maximum electron density of ionsphere and g is acceleration due to gravity.
