Web11 jun. 2016 · 4. RADIO WAVE PROPAGATION Radio Waves propagate outward from an antenna , at the speed of light. The exact nature of these waves is determined by the transmission medium. i.e., In free space they travel in straight lines , whereas in the atmosphere they generally travel in curved path. In a unguided medium, radio waves … Webslow decrease of the density in the ionosphere. The mean density distribution is also strongly dependent on the sun's activity. Fig 4.2 A picture of the temperature changes in the earths atmosphere. The properties and behaviors of the ionosphere, the region that will dictate radio wave propagation, will now be handled in depth.
