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.
Radio waves with frequencies below 30 MHz can bounce off the ionosphere and be sent back to Earth. This phenomenon is known as skywave propagation and is commonly used for long-distance communication. The ionosphere reflects these signals back to Earth, allowing them to travel beyond the line of sight.
The ionosphere helps to protect Earth from harmful solar radiation by absorbing and reflecting high-energy particles and radiation. Additionally, it plays a key role in enabling long-distance radio communications by reflecting radio waves back towards Earth's surface.
From what I have researched, the answer to that is the Ionosphere-upper mesosphere/ lower thermosphere, though I do not know if that is 100% correct.
The ionosphere contains ionized particles, such as ions and free electrons, that are created by the sun's radiation. It plays a critical role in radio wave propagation and reflects radio waves back to the ground, enabling long-distance communication. The ionosphere's density and composition can vary based on factors like solar activity and time of day.
It is what radio waves bounce off of.
The 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 lonosphere
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.
Radio waves with frequencies below 30 MHz can bounce off the ionosphere and be sent back to Earth. This phenomenon is known as skywave propagation and is commonly used for long-distance communication. The ionosphere reflects these signals back to Earth, allowing them to travel beyond the line of sight.
If you are talking about short waves then the ionosphere.
Any Amplitude Modulated radio signal will penetrate the ionosphere if its carrier frequency is high enough. Signals in the commercial AM broadcast band, with frequencies between 530 and 1700 KHz, aren't high enough. Most of their energy reflects from 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.
