which among the following is part of cathode ray tube?
Answers
Explanation:
The three main parts of a Cathode ray tube are:
• Electron gun: It gives out a fine beam of electrons.
• Deflecting system: It deflects the electron beam.
• Fluorescent screen: It is the part of the cathode ray tube on which the visual pattern of electron
Hi! I've named some of the main, basic parts of the cathode ray tude and attached a diagram to help you! Hope this is useful (≧◡≦)
The cathode-ray tube is a vacuum tube that contains one or more electron guns and a phosphorescent screen, and is used to display images. It modulates, accelerates, and deflects electron beam onto the screen to create the images. (i attached an image of it for you) Here are the parts of a cathode ray tube:
- The electron gun assembly: a device used in Cathode Ray Tube for displaying the image on the phosphorous screen of CRT. The electron gun emits electrons and forms them into a beam with the help of a heater, cathode, grid, pre-accelerating, accelerating and focusing anode.
- Phosphor viewing surface: a thin layer of material which emits visible light when struck by the electron beam.
- Glass envelope: The outer shell that gives a picture tube its characteristic shape is called the envelope of a cathode ray tube. The envelope is most commonly made of glass, although tubes of metal and ceramic can also be used for special purposes.
Have a good day/night, and I wish you the best grades in your next exams whenever they may be!
