The image illustrates the components and function of a cathode ray tube (CRT). **Components:**1. **Heated Filament (Source of Electrons):** Electrons are generated from this heated filament.2. **Cathode (-):** The negative electrode that emits electrons.3. **Anode (+):** The positive electrode that accelerates electrons towards the screen.4. **Electron Beam:** A stream of electrons that travels through the tube.5. **Conductive Coating:** Coating on the interior of the tube to guide and focus the electron beam.6. **Fluorescent Screen:** The front screen of the CRT that emits light when struck by the electron beam.**Diagram Explanation:**- The cross-section shows an electron beam being emitted from the cathode and accelerated by a uniform electric field towards the anode.- The electric field is represented with green arrows between the cathode and anode, indicating the direction of electron flow.- The electron beam continues to the fluorescent screen where it creates a visible image.- Coordinates (y, z) are given to show directional axes within the tube.This setup is typical of older television and computer monitors, utilizing the properties of electron flow and fluorescence to produce images. **CRT Electron Beam Deflection**In a Cathode Ray Tube (CRT), after electrons pass through the anode, they move in the z-direction at a speed of \(8.40 \times 10^6 \, \text{m/s}\). They then pass between a pair of vertical parallel plates (A) and horizontal parallel plates (B). Each plate is square-shaped with sides measuring 2.50 cm, and the separation between each pair of plates is 1.50 cm. The electric field between plates (A) is zero. However, as the electron beam exits the space between plates (B), it has been deflected 2.00 mm downward (\(\Delta y = -2.00 \, \text{mm}\)). The task is to determine the direction the beam is moving now. A positive value indicates the angle is below the horizontal, while a negative value indicates the angle is above the horizontal.**Diagram Explanation:**- **Electron Gun:** This component is responsible for emitting electrons.- **Heated Filament:** Acts as the source of electrons.- **Cathode (−) and Anode (+):** These elements help accelerate and direct the electrons.- **Plates (A) and (B):** Plate (A) manages horizontal deflection, while Plate (B) manages vertical deflection.- **Uniform Electric Field:** It is depicted alongside the plates to show interaction with the electron beam.- **Electron Beam Path:** The beam moves through the CRT, showing deflection before hitting the fluorescent screen.- **Fluorescent Screen:** This is where the electron beam eventually lands, providing visible feedback of the deflection.
