Radio waves are reflected by particles in the ionosphere. These waves are commonly used in long-distance communication because they can bounce off the ionosphere and travel long distances by reflecting and refracting off the charged particles in the Earth's upper atmosphere.
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.
An echo of a wave is exactly the same type of wave as the original wave. An echo is simply the original wave returning to the observer, so if you made a sound (a longitudinal wave of vibrating air molecules), the echo is also sound waves.
Transverse wave
A longitudinal wave is caused by the back and forth movement or vibration of particles. This type of wave involves the displacement of particles parallel to the direction of the wave itself.
When particles move up and down with a wave, this is known as vertical or transverse wave motion. In this type of wave, particles move perpendicular to the direction in which the wave is traveling. This motion creates crests and troughs in the wave pattern.
High-energy radiation such as gamma rays and X-rays are stopped in the ionosphere by interactions with the particles and magnetic fields present in this region of the Earth's atmosphere. The ionosphere acts as a shield, absorbing and scattering these types of radiation before they can reach the Earth's surface.

these ionised particles,reflect the radio wave to earth back.depending on the density of the ionosphere,at the time determins the amound of radio waves.this will affect clear reception.the height of the ionosphere involves reflecting angle,which gives long length hops.in this way long distance communications are affect by 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 layer of charged particles above Earth is called the ionosphere. It is located in the upper atmosphere and is ionized by solar and cosmic radiation, creating regions of varying density that affect radio wave transmissions and enable phenomena like the auroras.
longitudinal
The ionosphere is a region of the Earth's upper atmosphere containing ions and free electrons. It is composed of several layers of the atmosphere where solar radiation can ionize atoms and molecules, creating regions of charged particles that affect radio wave propagation and communication.
