Which knob is used to get a clear image on a microscope?
You use the Fine Adjustment Knob to give a very clear image on the microscope, mostly used on high power magnification.
What is fine adjustment of the microscope?
You use the fine adjustment to focus in HIGH power with a compound microscpe.
What is the use of the focusing knob on a microscope?
The answer is in the name. To focus the material or substance for a better/clearer view.
Why do scientists use the fine adjustment knob on a microscope?
It makes your vision more sharp and less blurry.
Why cant the coarse adjustment knob be used on high power lenses?
The coarse adjustment knob is used for making major changes to the focus, and is therefore too inaccurate to use at high powers, where only a very fine adjustment can drastically change the clarity of the picture you see.

Which focusing knob do you never use under high power?
The coarse adjustment knob should never be used when viewing in high power with a compound microscope. When in high power, use the coarse adjustment (the knob smaller than the coarse adj.) to more accurately focus on the subject.
High power on microscope?
On a the microscope I use, the ocular (eyepiece) has a magnification power of 10x. The 'low' (or 'scanning') objective lens is 4x, the 'medium' has a power of 10x, and the 'high' has a power of 40x. Multiply the ocular by the lens you're using to get your 'total magnification.' TIP: Only use the coarse adjustment knob while on 'low' power, then use the fine adjustment. Why? If you use the coarse adjustment knob on 'medium' or 'high,' there's a good chance you'll crack your slide. -BugCrunch
What part of the microscope should you used to focus the image when using high power objective lens?
First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.
What is the adjustment knob on a microscope?
The course adjustment knob raises and lowers the stage of the microscope. This knob is mainly used on the scanning and low power knob to simply find the specimen. When trying to focus directly, use the fine adjustment knob.
What is the correct microscope procedures?
Which of the following is a correct procedure for the operation of a microscope? First, put the specimen into focus using a low power lens, then switch to a lower power lens if needed.Remove and add slides while the high power lens is selected.First, put the specimen into focus using a low power lens, then switch to a higher power lens if needed.Use the fine focus knob with the low power lens and use the coarse focus knob with the high power lens
When using the high power objective which focus knob do you use?
The fine adjustment knob is used with the power objective on the microscope. Since the objective is already at the highest objective possible for that microscope, using the coarse adjustment knob would focus to much on the object making the details harder to read. Using the fine adjustment knob, you are able to see the fine details within the object or organism you are studying. The higher the power, the finer the knob and the lower the objective, the coarser the knob and objective.
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.
How does the procedure for using the microscope different under high power as oppose to low power?
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.

Which parts of a compound light microscope with clean lenses should be used to improve the quality of the image being observed in the high-power field of view?
You would use the diaphragm and fine-adjustment knob.
When do you use fine focus and the coarse focus knobs?
The fine focus knob is used to bring an object into fine focus, while the course focus knob is used to bring an object into approximate focus. The course focus knob should only be used on the low-power and scanning objectives of the light microscope. Using it on the high power microscope is okay, but you should be very careful. It is no recommended to use the course adjustment knob on the oil-emersion objective as it is so close to the stage and could lead to a potential break in the slide. Fine focus adjustment knob is useful to bring out the fine details in the specimen on your slide. Can be used on any of the objectives, but most receptive on the high-power and oil-emersion objectives.
