Radio

Radio is a technology that enables the transmission and reception of electromagnetic waves through the air. It is primarily used for communication and entertainment, facilitating the broadcasting of audio content such as music, news, and talk shows to a wide audience. Radio operates on different frequency bands, including AM (Amplitude Modulation) and FM (Frequency Modulation), each offering distinct sound quality and transmission range. It can also refer to the devices used to receive these signals, commonly known as radios, which convert radio waves into sounds that can be heard by listeners. Additionally, radio plays a significant role in emergency communication and information dissemination. The medium has evolved over time, with the advent of digital radio and internet streaming, but its fundamental purpose remains the same: to connect people through audio content delivered over varying distances.
