You do not use the coarse focus knob on high power because it can damage the slide and the objective lens of the microscope. Use only the fine focus knob to bring the specimen into sharp focus on high power.

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.


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.


Why should you never use the coarse adjustment knob on high power for a microscope?

Using the coarse adjustment knob on high power can potentially damage the microscope or the slide being observed due to the high magnification and close proximity of the objective lens to the slide. It is better to make coarse adjustments on low power to avoid hitting the objective lens against the slide.


Why should the course-adjustment knob on a microscope not be used with a high-power objective lens?

The course-adjustment knob moves the stage up and down quickly, and using it with a high-power objective can potentially damage the objective or slide due to a rapid change in focus. It is best to use the fine-adjustment knob when using a high-power lens for precise focusing.


How dows the procedure for using the microscope differ under high power as opposed to low power?

When using a microscope under high power, you typically start by locating the specimen using the coarse adjustment knob on low power before switching to high power for a more detailed view. Under high power, you may need to use the fine adjustment knob more delicately to focus due to the increased magnification. Additionally, the field of view is smaller under high power compared to low power.

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.

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.

Which knob on a microscope do you use to focus on low power?

You would use the coarse focus knob to focus on low power. Turn the coarse focus knob clockwise to bring the specimen into view and then fine-tune using the fine focus knob.


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 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


Why is it dangerous to focus using the coarse adjustment knob for on a microscope when using high power?

Using the coarse adjustment knob can lead to the objective lens crashing into the slide, potentially damaging both the lens and the slide. This is particularly dangerous when using high power magnification as the lens is closer to the slide. It is safer to only use the fine adjustment knob when focusing at high power to avoid this risk.
