Step-by-step solution for: Microscope Diagram (Grade 8) - Free Printable Tests and Worksheets
It looks like you've uploaded a labeled diagram of a compound light microscope, and the task is likely to identify the parts labeled A through K. Let's go step by step to identify each part and explain its function.
Here’s the identification and explanation for each labeled part:
---
A – Eyepiece (Ocular Lens)
- Function: This is the lens at the top that you look through. It magnifies the image produced by the objective lenses. Typical magnifications are 10x.
---
B – Coarse Adjustment Knob
- Function: Used to raise or lower the stage quickly to bring the specimen into approximate focus. It should only be used with low-power objectives.
---
C – Fine Adjustment Knob
- Function: Makes small adjustments to focus the image more precisely. Used after the coarse knob to achieve sharp focus, especially at higher magnifications.
---
D – Objective Lenses
- Function: These are the lenses located near the specimen. They provide the primary magnification. Most microscopes have multiple objective lenses (e.g., 4x, 10x, 40x, 100x). The total magnification is calculated by multiplying the eyepiece magnification by the objective magnification.
---
E – Revolving Nosepiece (Turret)
- Function: Holds the objective lenses and allows you to rotate between them to change magnification.
---
F – Stage Clips
- Function: These hold the glass slide in place on the stage so it doesn’t move while viewing.
---
G – Stage
- Function: The platform where the slide is placed for viewing. It may be mechanical (with controls) or fixed.
---
H – Diaphragm (Iris Diaphragm)
- Function: Controls the amount of light passing through the specimen. Adjusting it can improve contrast and clarity.
---
I – Light Source (Illuminator)
- Function: Provides light that passes up through the specimen. In modern microscopes, this is often an electric bulb or LED.
---
J – Base
- Function: The bottom support structure that holds the microscope together and provides stability.
---
K – Arm
- Function: The curved part connecting the base to the head. It supports the upper parts of the microscope and is used to carry the microscope.

| Label | Part Name | Function |
|-------|----------------------------|---------|
| A | Eyepiece | Magnifies image; you look through it |
| B | Coarse Adjustment Knob | Brings specimen into rough focus |
| C | Fine Adjustment Knob | Fine-tunes focus |
| D | Objective Lenses | Primary magnification lenses |
| E | Revolving Nosepiece | Rotates objective lenses |
| F | Stage Clips | Hold slide in place |
| G | Stage | Platform for slide |
| H | Diaphragm | Controls light intensity |
| I | Light Source | Illuminates specimen |
| J | Base | Supports the microscope |
| K | Arm | Connects base to head; for carrying |
