The waves that reach ionosphere (100-500km above earth surface), are refracted and sent back to earth. absorption reflection Ionosphere. Basics -Propagation LOS path WebSky waves suffer most of their absorption losses in the ionosphere. As a radio wave passes into the ionosphere, some of its energy is absorbed by the free electrons and ions. If these free electrons and ions do not collide with gas molecules, most of that energy is converted back into electromagnetic energy, and the wave continues.
