Radio Wave

Radio waves are a type of electromagnetic energy used for wireless communication, such as radio, television, and cell phones. They are invisible, travel at the speed of light, and have wavelengths longer than visible light. Radio waves are produced by transmitting devices and can travel long distances through the air, space, or even around obstacles. They work by carrying information—like sound or data—through variations in their wave pattern. Their ability to propagate over large areas and penetrate materials makes them essential for modern communication systems.
