What does CRT stand for?
Explanation
CRT stands for cathode ray tube. A cathode ray tube is a vacuum tube that contains an electron gun and a fluorescent screen. When an electric current is passed through the electron gun, it emits a beam of electrons which is directed towards the screen. The screen then emits light or displays an image when the electrons strike it. CRTs were commonly used in older television sets and computer monitors.Rate this question:

What color does the electron guns in a CRT use? (acronym)
Explanation
The electron guns in a CRT (Cathode Ray Tube) use the RGB color model. RGB stands for Red, Green, and Blue, which are the primary colors of light. By combining different intensities of these three colors, the electron guns can create a wide range of colors on the screen. Each electron gun is responsible for emitting one of these primary colors, and by varying the intensity of each gun, the desired color is produced. This color mixing technique is commonly used in CRT displays to generate a full spectrum of colors.Rate this question:

What happens when the phosphor coating is struck by electrons?
Explanation
When the phosphor coating is struck by electrons, it undergoes a process called electron excitation. This means that the electrons in the phosphor atoms absorb energy from the incoming electrons and move to higher energy levels. As these excited electrons return to their original energy levels, they release the absorbed energy in the form of visible light. This phenomenon is known as fluorescence and is the basis for the production of light in various devices such as fluorescent lamps and television screens.Rate this question:

Most CRTs use an __aspect ratio.
Explanation
Most CRTs use a 4:3 aspect ratio. The aspect ratio refers to the proportional relationship between the width and height of the screen. In a 4:3 aspect ratio, for every 4 units of width, there are 3 units of height. This aspect ratio was commonly used in older CRT (cathode ray tube) televisions and computer monitors. It is more square-shaped compared to the widescreen 16:9 aspect ratio that is commonly used in modern LCD and LED screens.Rate this question:
