Step-by-step solution for: Microscope Labeling
The image shows a compound light microscope with numbered parts. Below is the correct identification and explanation of each labeled part (1–14):
---
1. Eyepiece (Ocular Lens)
- This is the lens at the top of the microscope that you look through. It typically magnifies the image 10x.
2. Revolving Nosepiece (Turret)
- This is the rotating part that holds the objective lenses. You can switch between different objective lenses by rotating this piece.
3. Objective Lenses
- These are the lenses located below the nosepiece. They come in different magnifications (e.g., 4x, 10x, 40x). The total magnification is calculated by multiplying the eyepiece magnification by the objective magnification (e.g., 10x × 40x = 400x).
4. Stage Clips
- These hold the slide in place on the stage so it doesn’t move while you’re viewing it.
5. Stage
- This is the platform where the specimen slide is placed for viewing. It often has an opening to allow light to pass through the specimen.
6. Diaphragm (Iris Diaphragm)
- Located beneath the stage, this controls the amount of light passing through the specimen. Adjusting it helps improve contrast and clarity.
7. Condenser
- Focuses the light from the light source onto the specimen. It is usually located just below the stage.
8. Light Source (Illuminator)
- Provides the light needed to illuminate the specimen. In modern microscopes, this is often an electric bulb or LED.
9. Arm
- The curved support that connects the head (eyepiece) to the base. It’s used to carry the microscope.
10. Body Tube
- The tube that connects the eyepiece to the objective lenses. It maintains proper alignment between the lenses and the specimen.
11. Coarse Adjustment Knob
- This knob moves the stage up and down in large increments. Used initially to bring the specimen into focus.
12. Fine Adjustment Knob
- This knob makes small adjustments to focus. Used after coarse focusing to achieve sharp detail.
13. Base
- The bottom part of the microscope that supports the entire structure and houses the light source.
14. Foot (Base Support)
- The flat, stable bottom of the microscope that provides balance and stability.
