Radio and Television

Radio and television are communication technologies that transmit audio and visual content over distances. Radio uses electromagnetic waves to broadcast sound signals that can be received and played through a radio receiver, making it accessible for listening anytime. Television combines audio with moving images and allows viewers to see and hear content via a TV screen. Both rely on transmitting signals from a station to receivers using antennas or cables. They serve as powerful tools for entertainment, news, education, and advertising, reaching wide audiences efficiently and effectively.
