- ionosphere and magnetosphere
And AM radio waves, when they hit the ionosphere, they actually reflect back down.
- And AM radio waves, when they hit the ionosphere, they actually reflect back down.
- You got a lot of metal and energy and it produces in the ionosphere a super big peak in a thing called total electron count.
- You heat the ionosphere and you can guide the weather.
- So we've got now the sun, the ionosphere, the heat, and now we've got changing of the flora.
Examples
-
Solar activity also alters the ionosphere and affects radio wave propagation.
Academic text (2006) -
Radio waves bounce off the ionosphere, hundreds of miles up.
Fiction book (1995) -
And AM radio waves, when they hit the ionosphere, they actually reflect back down.
-
Over the whole Earth, the resistance between the surface and the ionosphere is about 200 ohms.
Academic text (1998) -
Management of communication frequencies relies on knowledge of the electron density in the ionosphere, which depends critically on solar activity.
Academic text (2006) -
The same law describes the Earth's ionosphere, a thick layer of ionized gas about 100 km above the Earth's surface.
Academic text (1999) -
During the day, the ionosphere helps in the transmission of radio signals over long distances.
-
The ionosphere, located between 50 to 600 miles above the Earth, plays a crucial role in reflecting radio waves.
-
Researchers monitored changes in the ionosphere to better understand how solar storms affect communication systems.

Etymology
Ionosphere is made from ion, meaning a 'charged particle', and sphere, meaning a 'round layer' as in atmosphere. So the word names the round layer of charged particles around Earth that can reflect radio waves.
