Ionosphere waves
Web29 mei 2024 · The ionosphere is a region of the upper atmosphere where there are large concentrations of free ions and electrons. …. In particular the ionosphere is widely known for affecting signals on the short wave radio bands where it “reflects” signals enabling these radio communications signals to be heard over vast distances. WebRadio waves below 40 MHz are signi cantly a ected by the ionosphere, primarily because radio waves in this frequency range are e ectively re ected by the ionosphere. The E and F layers are the most important for this process. For frequencies beyond 40 MHz, the wave tend to penetrate through the atmosphere versus being re ected.
