Web4 de ago. de 2014 · What happens with radio frequency is that electromagnetic waves are generated and radiated, not electrons. This is a consequence of current -i.e. the movement of electrons in a conductor (the antenna) driven by a time varying voltage. The current in the antenna generates both electric and magnetic fields and this field is radiated. WebRadio waves transmitted by antennas in certain directions are bent or even reflected back to Earth by the ionosphere, as illustrated in Figure 5. They may bounce off Earth and be reflected by the ionosphere repeatedly, …
