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)
The waves which are reflected back to the earth by ionosphere is
The wave which are reflected back to the earth by ionosphere is
On a particular day, the maximum frequency reflected from the ionosphere is 10 MHz The maximum electron density in ionosphere is
From which layer of the atmosphere,radio waves are reflected back?
Radio waves are reflected back to earth from the
Frequecies higher than 5 MHz are found not to be reflceted by the ionosphere on a particular day at a place. The maximum electron density of the ionosphere is
