Television

Television is a way of sending sound and pictures through the air. (1) ___________

Although John Logie Baird was the first to show how television worked, his success was based

on work by many other scientists from all over the world. (2) __________ The first television

service opened in 1936 in Britain. Colour television began in the United States in 1956.

At first, all television was black and white. Few people owned television sets because they

were very expensive. (3) ______________________________________

Television works by changing light waves into electric signals. This happens inside the TV

camera. A picture of what is happening in front of the camera forms on a special behind the

lens. Behind the screen is an electron gun. (4) _____________________ It moves from left to

right to cover each part of the picture. Each part is turned into an electric signal which is made

stronger, then sent to the transmitter as radio waves. They are picked up by home TV antennas

and changed back into electric signals. (5)________

The TV screen is covered with tiny chemical dots. In a colour set, these are arranged in

groups of three: one red, one blue, one green. At the back there are other electron guns. These

fire a beam of electrons to scan the screen just as the camera gun does. As each electron hits

the screen, it lights up a dot. (6)___________ You do not see lines of coloured flashing lights,

because the electron gun moves too fast for the eye to follow. What you see is a picture of

what is happening in the television studio.

(7)___________ Most programmes are recorded on film or videotape and sent out later.
