What is the difference between the course and the fine ajustment knobs?
The coarse adjustment knob is used for moving the objective lenses further away or closer to the specimen to roughly focus the image. The fine adjustment knob is used for making small and precise adjustments to the focus to sharpen the image and bring it into clear view.
What does the course adjustment do to a microscope?
A course adjustment knob on a microscope moves the stage or objective lens in large increments, allowing you to quickly bring the sample into rough focus. It is used to initially focus on the specimen before using the fine adjustment knob for finer focusing.
Why should you never use a course adjustment knob on High power?
Using the course adjustment knob on high power can cause the microscope to move too quickly, potentially damaging the specimen or the objective lens. It is better to use the fine adjustment knob on high power for precise focusing.
What does the fine-adjustment knob do on a microscope?
The fine-adjustment knob on a microscope is used to precisely focus the image by making small adjustments to the distance between the specimen and the objective lens. It allows for fine-tuning the focus of the microscope to get a clear and sharp image of the specimen.
Why should course adjustment not be used with high-power?
Course adjustment should not be used with high power because it can cause the microscope stage to move quickly and possibly crash into the objective lens or slide, causing damage. Additionally, using high power with course adjustment can result in a blurry image due to the rapid movement and lack of precision. It is better to use fine adjustment for precise focusing when using high power.

What is the function of the course adjusdment on a microscope?
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.
What is the use of the coarse adjustment knob?
The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.
