the big knob is called the coarse adjustment knob and the smaller one is the fine adjustment knob
coarse does a large scale focus, fine does such small scale focus you can only see a difference in how the (item under microscope) looks. You don't see the stage / nosepeice move up or down.

Which objective is used to focus light in a light microscope?
Adjustment knobs are used to focus light in a light microscope.
What is fine adjustment of the microscope?
You use the fine adjustment to focus in HIGH power with a compound microscpe.
Which object is used to focus light in a light microscope?
The lens is the object used to focus light in a light microscope. The lens in a light microscope is typically found within the objective lens or the eyepiece, and it helps to magnify the image of the specimen.
What is used to lower the lenses on a microscope?
The coarse adjustment knobs are used to to lower them dramatic amounts. And the fine adjustment knobs are used to lower them very small amounts, in order to focus in better on what you want.
What adjustment knobs is used with high power in a microscope?
The fine focus knob is typically used with high power in a microscope to make precise adjustments to the focus. This knob allows you to bring the specimen into clear view at high magnification without moving it out of focus quickly.

What are the 2 knobs on a microscope called?
There are two adjustment knobs (coarse and fine) on a microscope so you can move the stage at two different speeds. The coarse moves a lot per revolution, while the fine adjustment knob moves the stage at such small increments that it is nearly impossible to notice when looking from the side. The coarse adjustment knob should be used to get the stage closer to the lens only while you are looking at the microscope from the side. The fine adjustment knob can be used when you are looking into the microscope because there is a much lower chance of running the stage into the lens and breaking it.
What knobs are on the microscope?
Microscopes typically have knobs for adjusting the focus (coarse and fine adjustment knobs), magnification levels (objective lens turret), and the stage (stage control knobs for moving the specimen). Other common knobs include the condenser adjustment knob for controlling the amount of light passing through the specimen and the mechanical stage knobs for precise movement of the specimen.

What does the coarse-adjustment knob off of a microscope do?
It is the first knob you should turn to bring the object into rough focus, before tinkering with the finer tuning knobs.
What adjustment knobs is used with high power in a microscope?
The fine focus knob is typically used with high power in a microscope to make precise adjustments to the focus. This knob allows you to bring the specimen into clear view at high magnification without moving it out of focus quickly.
How do you use a microscope to view cells?
To view cells with a microscope, place a small sample of cells on a glass slide and cover it with a coverslip. Adjust the focus and magnification of the microscope to view the cells clearly. Use the fine and coarse adjustment knobs to bring the cells into focus.
Fine adjustment of microscope?
To make fine adjustments on a microscope, use the fine focus knob to sharpen the image. This knob allows you to bring the specimen into clear focus by moving the objective lens slightly up or down. Use it after using the coarse focus knob to roughly focus the image. Make small, careful movements until the specimen is sharply in focus.
What is the procedure for focusing a microscope using the coarse and fine adjustment knobs?
To focus a microscope using the coarse adjustment knob, gently turn it in one direction until the specimen comes into view. Then, use the fine adjustment knob to further sharpen the image. Avoid using excessive force on either knob to prevent damaging the microscope or specimen.
