Step-by-step solution for: Microscope Labeling
The image shows a compound light microscope with numbered parts that need to be labeled. Below is the correct identification of each part, along with a brief explanation of its function.
---
1. Eyepiece (Ocular Lens)
- This is the lens at the top of the microscope where you look through. It typically magnifies the image 10x.
2. Revolver (Nosepiece)
- The rotating part that holds the objective lenses. You turn it to switch between different magnifications.
3. Objective Lenses
- These are the lenses located below the revolver. They come in different magnifications (e.g., 4x, 10x, 40x). The total magnification is calculated by multiplying the eyepiece magnification by the objective lens magnification.
4. Stage Clips
- These hold the slide in place on the stage so it doesn’t move while you’re viewing it.
5. Stage
- The flat platform where the slide is placed for observation.
6. Diaphragm (Iris Diaphragm)
- Controls the amount of light that passes through the specimen. Adjusting it can 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 part that connects the head (with the 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 the proper distance between the lenses and the specimen.
11. Coarse Adjustment Knob
- Used to move the stage up and down quickly to bring the specimen into rough focus.
12. Fine Adjustment Knob
- Used for fine-tuning the focus after using the coarse knob. It makes small adjustments to achieve sharp focus.
13. Base
- The bottom part of the microscope that supports the entire structure and houses the light source.
14. Foot (Base Support)
- The wide, stable bottom that keeps the microscope balanced and upright.
