Why is the ionosphere important for communication?
It is what radio waves bounce off of.
What do radio waves bounce off?
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.
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 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 is the outermost and biggest layer of earth atmosphere?
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.
radio waves heading upward from earth often bounce off the ____.?
ionosphere
Can radio waves bounce off stars?
Yes they can
Radio waves bounce and return to earth?
The Radio waves are reflected back to Earth in the Ionosphere.
Why is ionosphere important for communications?
It is what radio waves bounce off of.
Radio waves headed upward from earth often bounce off the?
thermosphere-apex
Neither X rays nor radio waves can penetrate the earth's atmosphere?
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.
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
