Question
For sky wave propagation of MHz signal, what should be the minimum electron densty in ionosphere?
Options
A.~ 1.2 × 1012 m-3
B.~ 106 m-3
C.~ 1014 m-3
D.~ 1022 m-3
Solution
From equation 
107 = 9μmin1/2
⇒  9μ =
= 1.2 × 1012 units
107 = 9μmin1/2
⇒  9μ =
= 1.2 × 1012 unitsCreate a free account to view solution
