ionosphere
The Radio waves are reflected back to Earth in the Ionosphere.
The Ionosphere reflects longer radio waves back to Earth. It varies in height going up at night giving the waves a long distance bounce.Flat vertical walls. Better refraction will Non-ferous metals. Horizontal plan will distort the image of the wave.\ CIV
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.
it is the thremosphere i am taking the apexvs text and i got it right

The ionosphere there are particles called ions in the ionosphere (hens the name). The ions cause radio waves from am radio stations to bounce off of it.
Actually, radio waves do go out into space. However, depending on frequency, they do tend to bounce off of the ionosphere, which is why lower frequency waves such as AM and longwave have greater (on Earth) range than higher frequency waves, such as FM or microwave.
Radio waves, like all forms of electro magnetic radiation are affected by gravity, so the Earth's mass helps to bend the radio waves to an extent. Beyond that, radio waves can be reflected naturally by atmospheric conditions, but generally, when a radio signal needs to be transmitted a significant distance, it is done by a series of radio towers in relay.AnswerThe condition is called 'skip'. The waves bounce off the ionisphere and back to earth way past the curvature.
A.M. radio tends to hug the Earth and will bounce off of the ionosphere. Commercial F.M. is 100 times the frequency of commercial A.M. and tends to travel in straight lines and will head off into space.
Because of all the EM radiation we receive from the sun.Also . . .we can see the moonwe can see the sunwe can see other starswe can communicate by radio with astronauts on the moonwe can communicate by radio with the Curiosity on Marswe can communicate by radio with our space probes that have left the solar systemwe can bounce light and radio from Earth to moon and back to Earth
