Ionosphere formation
Le rayonnement ultraviolet solaire qui est à l’origine de l’ionosphère réagit sur une partie des molécules atmosphériques en les amputant d’un électron. Un plasma, qui contient des nombres égaux d’électrons et d’ions positifs, est ainsi créé. L’électron, qui est léger, reçoit une vitesse considérable de façon que le gaz électronique obtient une température élevée (de l’ordre de mille kelvins) bien a… WebThe ionosphere regions can absorb or dampen radio signals, or they can bend radio waves, as well as reflecting the signals as described above. The specific behavior …
