Answer

Answer:

A television receives a signal containing separate picture and sound information. In a cathode-ray tube television, an electron beam scans the screen and makes phosphors glow to form the image. The audio signal is sent to speakers, which vibrate to produce sound. Together, these processes display the picture and play its matching sound.
