Radio waves bounce off of the ionosphere and return back to Earth.
Radio waves reflect off the ionosphere. The ionosphere is composed of ionized particles that can refract and reflect radio waves, allowing for long-distance communication through the atmosphere. The ability of radio waves to bounce off the ionosphere is important for services like shortwave radio and over-the-horizon radar.
The section of the atmosphere known for its ability to bounce shortwave radio signals is the ionosphere. This region, located approximately 30 miles to 600 miles above the Earth's surface, contains ionized particles that reflect radio waves back to the Earth, allowing for long-distance communication. The ionosphere's reflective properties are particularly effective for shortwave frequencies, making it essential for radio broadcasting and international communication.
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.
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
I dont think they do, Radio waves diffract less and arn't affected by the ionosphere which is the upper part of the atmosphere. Most electromagnetic waves are affected severely by the atmosphere, which is a good thing due to the strength they carry EXCEPT microwaves *Apparantly*.
ionosphere
Yes they can
It is what radio waves bounce off of.
The Radio waves are reflected back to Earth in the Ionosphere.

False. For some bands of radio waves the atmosphere is transparent. Radio waves can penetrate to the ground. That's why we have radio telescopes on the Earth.
