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 chemicallytreated screen, on which the object is
reconstituted by means of glowing dots.
