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.

radio waves heading upward from earth often bounce off the ____.?
ionosphere
Can radio waves bounce off stars?
Yes they can
Radio waves headed upward from earth often bounce off the?
thermosphere-apex
Radio waves bounce and return to earth?
The Radio waves are reflected back to Earth in the Ionosphere.
Which has a higher frequencies am radio waves or fm radio waves?
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
Why is the ionosphere important for communication?
It is what radio waves bounce off of.
Part of atmosphere used to bounce shortwave radio waves?
Radio waves bounce off of the ionosphere and return back to Earth.

What kind of radio waves bounce off an object to determine its speed and location?
radar
What weather instrument sends out radio waves to see hundreds of kilometres?
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.
What layer of the atmosphere do radio waves heading upward from earth often bounce off?
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
What keeps radio waves and such from soaring off of earth into space?
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.
