Radio Frequency (RF) refers to the electromagnetic waves that fall within the frequency range of 3 kHz to 300 GHz. These waves are used for various forms of communication, including radio, television, and cellular networks. RF technology enables the transmission of information over long distances without the need for physical connections, making it essential for modern communication systems. RF waves are generated by oscillating electric and magnetic fields, which can travel through the air and other mediums. Devices such as transmitters and receivers are used to send and receive these signals. RF is also utilized in applications like radar, microwave ovens, and wireless internet.
