Using the coarse adjustment knob on high power may cause the objective lens to come in contact with the slide, potentially damaging both the lens and the slide. It can also lead to misalignment of the optics, resulting in blurry images and potential damage to the microscope.

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 would you never use the coarse adjustment knob on high power?

The coarse adjustment knob may move the lens too far too fast and the slide may crack and/or the object be squashed. Using the fine adjustment lens will bring the object into focus much more accurately. In addition, the coarse adjustment knob adjusts in too great a quantity. The fine is less responsive so its easier to adjust at high magnification.


Why should you never use the coarse adjustment on higher power?

Using the coarse adjustment on higher power can risk damaging the lens or the slide because the distance between the lens and the slide is very small. It can also cause the objective lens to hit and break the coverslip or slide. Finer adjustments should be made with the fine adjustment knob when using higher magnifications to prevent this.


Why is coarse adjustment knob not commonly used when focusing under high power objective?

The coarse adjustment knob moves the objective a lot while the fine adjustment knob moves it just a little, so using the coarse knob under high power can cause the objective to hit the slide and potentially damage the slide or the objective. The fine adjustment knob provides more precise control for focusing under high power, allowing for better clarity and accuracy.


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.


The coarse adjustment knob on a microscope should never be used with the?

The coarse adjustment knob on a microscope should never be used with the high-power objective lens. This can cause damage to both the lens and the slide being viewed. Instead, it is best used with the low-power or scanning objective lens for initial focusing.

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 name of the adjustment knob that moves the body tube for focusing with the high-power objective lens?

The adjustment knob that moves the body tube for focusing with the high-power objective lens is called the fine focus adjustment knob. It allows for precise adjustments to bring the specimen into sharp focus at high magnifications.


Why should you never us the coarse adjustment knob on high power?

Because the movement is too large and you can break the slide of you turn it the wrong way.

6 How does the procedure for using the microscope differ under high power?

For low power you can use the coarse adjustment and fine adjustment for 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.

How does the procedure for using the microscope differ under high power as opposed 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.

Why coarse adjustment screw being used with low power objective?

The depth of field is so small that a very small vertical travel could shift the focus from the top of the specimen to the bottom. A very fine adjustment must be used, which is why the coarse adjustment screw is implemented.
