Radio

Radio is a technology that uses electromagnetic waves to transmit and receive audio signals over distances. It operates by converting sound into radio waves, which can travel through the atmosphere. The main components of radio systems include a transmitter, which sends out the radio waves, and a receiver, which captures and converts the waves back into sound. Radio technology is widely used for various applications, including broadcasting music, news, and information, as well as for communication purposes, such as two-way radio systems. The medium of radio can be AM (Amplitude Modulation) or FM (Frequency Modulation), each with its characteristics and applications.
