The way the television works

• The way television works is that
• variations in light from an object produce
  electric impulses in a photo-electric cell.
  These electrical impulses are magnified
  enormously by a valve. The impulses can be
  trapped by a radio but instead of going through a
  loud-speaker, they are fed into a cathode ray
  tube. There they form tiny streams of electrons
  that impinge on a chemically-treated screen, on
  which the object is reconstituted by means of
  glowing dots.
