Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. They are used for various forms of communication, including television, radio, and cellular networks. Their ability to travel long distances makes them essential for transmitting information without the need for physical connections. These waves are generated by oscillating electric charges and can be produced by various devices, such as transmitters. Radio waves can be modulated to carry information, allowing for the transmission of audio, video, and data. Their versatility and efficiency have made them a cornerstone of modern communication technology.
