Radio technology involves the transmission and reception of electromagnetic waves to communicate information over distances. It works by converting sound or data into radio waves, which are then sent through the air. These waves can travel long distances and are used in various applications, including broadcasting, cellular communication, and satellite communication. At the receiving end, a radio device captures these waves and converts them back into sound or data. This technology is essential for everyday activities, such as listening to music, making phone calls, and accessing the internet wirelessly.
