Vacuum tubes must be used in order for cathode rays to work. Cathode rays involve electrons. When the electrons are placed in the vacuum tubes, this causes the cathode rays. The way in which the cathode ray tubes work is that the electrons are in the vacuum tubes and the electrons are negatively charged. Since they are negatively charged, they repel or turn away from the cathode because it is negative too.


They move to the positive part of the tube. That is how they move because they are traveling to what they are attracted to. They also travel straight to the positive part. They move in a straight line from point a to point b. Then the electrons move quite fast.

Cathode ray tubes are technology used to ultimately procure a picture. A cathode ray tube takes an incoming electronic signal and turns it into an electron stream, which creates an image he combined with certain substances. More specifically, negative electrons are deflected by the cathode to positively charged plates. The larger the picture, the greater the deflection; as the cathode ray moves horizontally across a scene. Sound familiar?


Cathode ray tubes are the most common technology used in computer monitors and televisions. For this reason, the signal needs to be constantly refreshed even if the colors don’t change. Cathode ray tubes are a less expensive alternative to LCD or plasma screens. They are also used in various medical monitors and oscilloscopes. So, electrons are not just a part of cathode ray tubes, they are everything needed to make it functional. Without electrons, cathode ray tubes would be useless and have nothing to produce.
