jonosfärsreflektion
Jonosfärsreflektion refers to the phenomenon where radio waves are reflected by the ionosphere, a region of Earth's upper atmosphere. This reflection is crucial for long-distance radio communication, particularly for shortwave radio frequencies. The ionosphere is a layer of the atmosphere containing ionized particles, created by solar radiation. These ionized particles, essentially charged atoms and molecules, affect the propagation of radio waves.
When radio waves enter the ionosphere at a certain angle, they can be bent or refracted by
