I assume you would use the fine adjustment knob for high power objectives.

What must NEVER be used when using the medium or high power objectives?
The coarse adjustment because it moves the objective much farther than the fine adjustment knob, and you could hit the slide with the objective and damage the lens and/or the slide.
Turning which knob moves the objective lenses the greatest vertical distance?
coarse focus. This was by Joseph, hi R.C.S
What is the function of coarse focus adjustment knob on the microscope?
The function of a microscope's coarse adjustment knob is to improve focus on the object under study by adjusting the lens. Unlike the fine adjustment, coarse adjustment moves the lenses quickly.
Why is fine adjustment used for high power?
Because if you use coarse adjustment, the body tube of the microscope (the part that moves up and down when you turn the knobs) will hit the microscope slide and cause the slide to break/crack. It moves the tube very quickly . You also run the risk of damaging the high power lens when it hits the slide. The fine adjustment only moves the tube a teeny tiny bit and very slowly so you don't have a great of a risk of damaging the slide or lens. The fine adjustment also helps to focus slowly so you don't miss the object you're trying to see.
What is the function of the fine adjustment knob?
Assuming that you were talking about a microscope, then . . . the fine adjustment is really the normal adjustment. It's easy to use to get a great focus because it moves the focusing mechanism very little per turn. On the other hand, the fine adjustment simply won't get you close to initial focus without spending a day or two turning the dern thing. On the other hand, the COARSE focusing knob will get you NEARLY to correct focus in a flash.
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.
What moves the body tube or stage up and down for focusing?
Course Adjustment and Fine Adjustment Knobs.

What does the focusing knob on a microscope do?

What must NEVER be used when using the medium or high power objectives?
The coarse adjustment because it moves the objective much farther than the fine adjustment knob, and you could hit the slide with the objective and damage the lens and/or the slide.
What is the function of the stage adjustment knob?
the stage adjustment knob is a knob that moves the stage go up anad down . you should use it on a lower power objective lens though
Why must the course adjustment knob be turned forward only while watching from the side?
The course adjustment knob must be turned forward only while watching from the side to ensure that the microscope's objective lens moves closer to the specimen. This allows for focusing on the specimen and achieving a clear image. Turning the knob in any other direction may result in moving the objective lens away from the specimen, leading to an out-of-focus image.
Why should you only use the fine adjustment when the high power objective is in position?
Because if you use the coarse adjustment under high power, there is a greater risk that you will crack the slide on the microscope and damage it. The fine adjustment only moves the objective lense small amounts and very slowly, so there is no chance that you will damage the slide.
Moves the body tube up and down on the microscope?
Coarse adjustment moves it visibly and fine adjustment moves it only slightly
Turning which knob moves the objective lenses the greatest vertical distance?
coarse focus. This was by Joseph, hi R.C.S
