Answer:

The deflecting system is responsible for deflecting the beam of electrons in accordance with input signals to produce a pattern.

Function of deflecting system in CRT

The cathode ray tube (CRT) is an evacuated glass envelope containing an electron cannon, an electron source, and a fluorescent light, typically with internal or external methods to accelerate and redirect the electrons. It was invented in 1897 by German physicist Karl Ferdinand Braun. When electrons collide with a fluorescent tube, light is emitted.

The electron beam is deflected and modulated in a manner that allows an image to appear on the projector. The picture may reflect electrical wave forms, photographs, echoes of radar-detected aircraft, and so on. The single electron beam can be processed to show movable images in natural colours.
