The ionosphere. To clarify, only the low-frequency radio waves incorrectly called "high-frequency" or "HF" of about 50MHz and below are reflected. "Very High Frequency" VHF signals are not reflected, but go straight off into space.
For example, in the "AM" commercial broadcast spectrum, the transmission is reflected back to the Earth and is receivable for great distances, a phenomenon that used to be called "skip". AM signals are in the band of 550KHZ to 1.6 MHz. "FM" stations in the band from 88MHz to 108MHz are only received by "Line of sight" transmissions.
The ionosphere is the atmospheric layer that contains electrically charged particles. It is located between the mesosphere and the exosphere and plays a key role in the propagation of radio waves and the formation of auroras.
Plasma is a state of matter that consists of electrically charged particles. Plasma is found in stars, lightning, and neon lights, among other things.
Yes, liquids can contain electrically charged particles, such as ions. In some liquids, molecules can dissociate into ions, carrying positive or negative charges. These charged particles can contribute to the electrical conductivity and other properties of the liquid.
The vibration of electrically charged particles can produce electromagnetic waves, such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Lightning was not invented; it is a natural phenomenon that occurs when electrically charged particles in the atmosphere are discharged. Lightning is a result of the build-up and release of electrical energy in thunderstorms.
In air Atmosphere it is Ionosphere.
The ozone layer contains electrical charged particles that reflects radio waves
The ionosphere - specifically the e-layer
protons
yes ions are electrically charged particles in the troposphere
Electrically charged particles are found in the ionosphere, a region of the Earth's upper atmosphere that extends from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth's surface. The ionosphere contains ions and free electrons that are formed due to the ionization of molecules by solar radiation.

Auroras are caused by electrically charged particles from the sun interacting with the Earth's magnetic field. When these particles collide with gases in the Earth's atmosphere, they produce beautiful light displays known as auroras.
The region within the lower portion of the thermosphere where particles become electrically charged is called the ionosphere. This layer of the atmosphere contains a high concentration of ions and free electrons, which allows it to reflect radio waves and facilitate long-distance communication.
