radio waves heading upward from earth often bounce off the ____.?
ionosphere
Radio waves headed upward from earth often bounce off the?
thermosphere-apex
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
How does the ionosphere help radio transmission?
Radio signals at a frequency below 30 mHZ can bounce off the ionosphere and be reflected back to earth. This is often referred to as DX skip. Sometimes, sunlight will excite the ions enough to where there'll form more dense spots within the ionosphere. These can, at times, allow higher frequency transmissions to use the same DX skip, although frequencies higher than 30 mHZ will normally pass right through it.
How do you communicate with astronauts if radio waves are reflected back to earth?
Radio signals at frequencies up to roughly 40 to 60 MHz are absorbed or reflected from the ionosphere. At higher frequencies, the signals easily penetrate the ionosphere and continue on into space. This is the reason that AM radio (1 MHz) and "short-wave" broadcasts (4-13 MHz) are often received from great distances, but TV (54 MHz and up) and FM radio (100 MHz) are not.

What is atmospheric bounce and how is it beneficial?
Atmospheric bounce is a technique used by Amateur Radio operators - to increase the distance their signals travel. Some frequency bands in use by amateur radio enthusiasts have a limit on the amount of power their equipment can produce. This often restricts the distance their signals can travel (sometimes to just a few miles). By using atmospheric bounce, an operator can 'reflect' the radio signal off the upper atmosphere (like shining a torch on a mirror) and thus the range can be (often dramatically) increased.
Why are titles often omitted in the heading information on a memo?
The titles are often omitted in the heading of a memo because the should be proper spacing in the paragraphs.
How spacewave came back to the earth?
Radio waves are often referred to as space waves because they have the ability to move through space. Radio waves are a type of electromagnetic radiation.
What does it mean when a person says their hair has no bounce?
When a person says their hair has no bounce, they are referring to their hair being flat. Persons with straight hair often complain of this as straight hair is often flat.
Was Obama bounce in the convention 2012?
Yes, as often happens for both parties, there is a bounce after a convention. This refers to a boost in the candidate's poll numbers. The president definitely got a bounce after the Democratic convention.

Why does the moon often look shiny?
If the moon is not blocked by the earth it will shine. Why? Because stray light rays bounce off the surface of the moon. It looks like the moon is giving off its own light, but no.
Is bounce a onomatopoeia?
No it isn't. "Boing" is a word often associated with bouncing, and it is an onomatopoeia.
