In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Si
Radio waves (black) reflecting off the ionosphere (red) during skywave propagation. Line altitude in this image is significantly exaggerated and not to scale.

Ionosphere
Videos
The ionosphere is the ionized part of the upper atmosphere of Earth, from about 48 km to 965 km above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The
