Answer 2

Towards the back of the tube there is a cathode that accelerates electrons to high energies, there are magnetic deflectors that move the beam (ray) of electrons to different positions on the screen where the electrons activate red, green or blue phosphors creating the image. (Cathode Ray Tube) This happens really quickly and the electron beam sweeps across the entire screen in just a few milliseconds, the phosphors glow for several hundredths of a second so you see very little blinking.

Answer 3

CRT is a vacumn tube which are controlled by electic or magnetic field

Answer 4

A CRT monitor contains millions of tiny red, green, and blue phosphor dots that glow when struck by an electron beam that travels across the screen to create a visible image.
