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.

What is zone of the atmosphere which affects the transmission of radio waves?
Ionosphere
What level of atmosphere bounces off radio waves off of the earth?
Radio waves are in all parts of the atmosphere. Some, but not all, radio waves are reflected from the ionosphere, permitting transmission over greater distances.
The region of the atmosphere that reflects radio signals is the?
The Ionosphere.
Radio waves bounce and return to earth?
The Radio waves are reflected back to Earth in the Ionosphere.
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.
Which of the atmospheric layers makes radio transmission possible?
ionosphere

Ionosphere

How does the ionosphere help us?
The ionosphere has the useful property of reflecting radio waves, thereby enabling us to send radio signals past the horizon.
What important quality does the ionosphere?
the ionosphere is important is the it is in the thermosphere
What is the effects of ionosphere on transmission?
Ionosphere consists of ionised species which reflect the radio waves that are directed towards it.Thus it redirects the radiowaves towards the target.This avoids the radio waves getting obstructed by ground wave propogation.
This layer is responsible for the possibility of radio communication?
The Ionosphere
The region of the atmosphere that reflects radio signals is the?
The Ionosphere.
Radio waves bounce and return to earth?
The Radio waves are reflected back to Earth in the Ionosphere.
How can ionOsphere can help us communicating?
