it refracts the radio waves back towards the earth
The Radio waves are reflected back to Earth in the Ionosphere.
It is the ionosphere, a general region that includes all of the thermosphere and parts of the two bordering layers. In this region, between 60 and 1000 kilometers above the Earth, ionized particles refract and reflect radio waves back toward the ground. This enables radio transmissions that are normally "line of sight" only to reach over the horizon for hundreds or thousands of miles. This includes broadcast radio (HF) and shortwave bands.
Radio waves are in all parts of the atmosphere. Some, but not all, radio waves are reflected from the ionosphere, permitting transmission over greater distances.
AM waves are reflected by earth's ionosphere
ionosphere
The ionosphere contains weakly ionized gas which reflects radio waves.
thermosphere-apex
Radio waves bounce off of the ionosphere and return back to Earth.
ionosphere
The "ionosphere".
Radio waves are reflected by many solid objects, such as wood, stone, and notably metal, allowing the use of microwaves in radar applications.Also importantly in broadcast radio, the ionosphere (an upper layer of the Earth's atmosphere) can bounce signals back down to locations beyond the line-of-sight horizon.
