The lower layers, the D and E layers are only a few tens of km - perhaps a hundred km at most. The F layers are of greater importance for ionospheric reflection, and may be up to 250 km. May be useful up to 800 km.
These various layers have a frequency - dependent reflectivity, and this will change day and night according to the state of ionization and the illumination causing that.

How far away is the Ionosphere from earth surface?
274 k
What is ionosphere?
The ionosphere is a layer of the Earth's atmosphere that is ionized by solar radiation.
How the sunspot affect the earth?
The primary affect on the Earth is on our ionosphere
How many miles high is the ionosphere?
test
How is the ionosphere helpful to man?
The region of the atmosphere located from 53 to 370 miles altitude is called the ionosphere. This space is ionized by solar radiation, which makes it incredibly helpful to mankind. Because of the ionosphere we are able to form radio propagation all over the earth as well as make consistent advances in geophysics.
How far from earth is the ionosphere?
274 kilometers from the earth exactly.
How far is the ionosphere from earth's surface?
274 kilometers from the earth exactly.
How far away is the Ionosphere from earth surface?
274 k
What is ionosphere and what does it do?
The ionosphere is the part of the earth's atmosphere extending from about 30 miles (50 Kilometers) to the exosphere that contains ionized atmospheric gases. it influences radio propagation to distant places on the Earth.
What is the ionosphere and were is it?
The ionosphere is a layer of earths atmosphere. It is charged with a high concentration of ions. It is above the mesosphere about 50 t0 600 miles above the earth.
Radio waves bounce and return to earth?
The Radio waves are reflected back to Earth in the Ionosphere.
Which is the farthest from earth Troposphere Stratosphere Ionosphere or Mesosphere?
the Ionosphere is the farthest away from the earth =)
What is the vegetation of the aurora lights?
The aurora occurs in the ionosphere of the earth, over 60 miles (80 km) above the surface of the earth. There is no vegetation there.
What is ionosphere?
The ionosphere is a layer of the Earth's atmosphere that is ionized by solar radiation.
Radio signals are bounced back to earth by this layer?
ionosphere <novanet>
Which Atmospheric layer reflects radio wave?
It is the ionosphere, a general region that includes all of the thermosphere and parts of the two bordering layers. In this region, between 60 and 1000 kilometers above the Earth, ionized particles refract and reflect radio waves back toward the ground. This enables radio transmissions that are normally "line of sight" only to reach over the horizon for hundreds or thousands of miles. This includes broadcast radio (HF) and shortwave bands.
How far is the earth from the inosphere?
first of all thing considered, its ionosphere. and to the question it is 60000000 millimeters into the sky or 60 kilometers in the sky.
