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.
A radio sends its electromagnetic waves into the ionosphere where they bounce back to earth.

The Radio waves are reflected back to Earth in the Ionosphere.
FM radio has the higher frequency which is why it sounds better. AM is a lower frequency but can travel further because the waves bounce off
It is what radio waves bounce off of.
Radio waves bounce off of the ionosphere and return back to Earth.

radar
You may be thinking of weather RADAR. It sends out radio waves, some of them bounce off of rain, snow, or the boundaries of layers in the atmosphere, and the radar receiver detects the waves that bounce off of something and come back.
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
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.
