What is Cathode Ray Tube?
Cathode ray tube is a empty tube in which cathode rays hit the tube’s surface due to which it generates images on the bright screen. They are normally used in televisions and computers.
As the electrons are negative in nature they are attracted by anode. And the anode acts as accelerator and these high speed electrons hit the screen which emits light on the bright screen by forming millions of dots called pixel.
Back of the monitor it is provided with electron gun with cathode and anode which are used as reference elements for positive and negative elements. When cathode ray is produced in the glass vacuum tube it releases flow of electrons through the ray.
Cathode ray tube is also known as picture tube which is found in all electronic television sets for displaying images on the screen.
These cathode ray tubes are also used in computer monitors, automated teller machines, video game machines, video cameras, oscilloscopes and radar displays.
