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.
Ionosphere
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 Ionosphere.
The Radio waves are reflected back to Earth in the Ionosphere.
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.

The Ionosphere.
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.

The ionosphere has nothing to do with radioactivity, and there is nothing in nature that is called a "radio active wave."Because the ionosphere contains electrical charges, it is able to reflect radio waves.
The ionosphere helps us by reflecting radio waves, which enables long-distance radio communication. It also plays a crucial role in regulating the Earth's climate by absorbing harmful ultraviolet radiation from the sun. Additionally, the ionosphere allows for the existence of phenomena like the Northern Lights.
The ionosphere is the layer responsible for enabling long-distance radio communication by reflecting radio waves back to Earth. Its charged particles interact with radio waves, bending and reflecting them to facilitate communication over long distances. Without the ionosphere, radio waves would continue into space, limiting long-distance communication possibilities.
Radio waves reflect off the ionosphere. The ionosphere is composed of ionized particles that can refract and reflect radio waves, allowing for long-distance communication through the atmosphere. The ability of radio waves to bounce off the ionosphere is important for services like shortwave radio and over-the-horizon radar.
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
