As you rack the fine adjustment up, the air bubble will appear to move in the opposite direction. Similarly, as you rack the fine adjustment down, the air bubble will appear to move in the same direction. This movement is due to the changes in the position of the objective lens that affects the focus and the path of the light passing through the microscope.
The coarse adjustment knob moves the stage up and down quickly, while the fine adjustment knob allows for precise focusing.
The coarse adjustment on a microscope is used to initially focus the specimen by quickly moving the stage up or down. It is used to bring the specimen into view before fine-tuning the focus with the fine adjustment knob.

The coarse adjustment knob brings objects into rapid focus by quickly moving the stage up or down. It is used first to focus roughly on the specimen before fine-tuning with the fine adjustment knob.
Coarse adjustment on a microscope is a large focusing knob or wheel that moves the objective lenses up and down to quickly bring the specimen into rough focus. It is used to approximately focus on the specimen before fine-tuning the focus using the fine adjustment knob.
The coarse adjustment (up or down) is used to quickly move closer to or away from the focal point of the specimen. The fine adjustment is then used to fine tune the focus and bring the specimen into clear view.Coarse adjustment means big movements up or down. Fine adjustment means very small movements until the specimen is in focus.
The coarse adjustment knob moves the stage up and down quickly, while the fine adjustment knob allows for precise focusing.
The coarse adjustment knob elevates the microscope's stage up and down quickly. The fine adjustment knob does the same thing but more slowly and accurately. In other words, the fine adjustment knob should require more revolutions to elevate the stage as much as the coarse adj. knob does.
The course adjustment on a microscope is used to focus on the specimen initially. It is a larger adjustment that moves the stage up and down quickly to bring the specimen into view. Once the specimen is roughly in focus using the course adjustment, the fine adjustment knob is used to fine-tune the focus.

The coarse adjustment knob is used to bring the specimen into approximate focus quickly. It moves the objective lens or the stage up and down in larger increments to roughly focus the image before using the fine adjustment knob for fine-tuning the focus.
To focus on a specimen using a microscope, you will typically use the coarse adjustment knob for initial focusing and the fine adjustment knob for precise focusing. The coarse adjustment knob moves the stage up and down quickly to bring the specimen into view, while the fine adjustment knob allows for small, precise adjustments to achieve a clear image.

The Fine Adjustment
Use a coarse adjustment knob (large movement) to get near, then use the fine adjustment knob (small movement) to fine-tune.
