The correct answer is option 1 - Ionosphere. The Ionosphere is the layer of the Earth`s atmosphere that extends from about 60 kilometers (37 miles) above the Earth`s surface to about 1,000 kilometers (621 miles) above the surface. This layer is characterized by a high concentration of ions and free electrons. Radio waves are reflected back to Earth in the ionosphere due to the presence of these ions and free electrons. This reflection allows for long-distance communication using radio waves, as they can bounce off the ionosphere and travel great distances. The ionosphere plays a crucial role in radio communication, including both shortwave radio and satellite communication.
