Why should you never rack downwards with the coarse focusing while you are looking down the microscope?

The object on the viewing stage is close to the lens of a microscope. Racking downward risks the lens touching the object and damaging either the object itself or the lens. Before moving the lens down, make sure you can see the lens and the object from the side of the microscope to void the two touching each other.

Which country has more gravity?

Gravity is quite constant everywhere on Earth. Slightly more at lower elevations, slightly less at higher ones, but never enough so that you would notice the difference. There's no country on Earth that has generally more or less gravity than others have.

What is the furthest point south where the sun never gets exactly overhead at noon?

The furthest point south where the sun never gets exactly overhead at noon is the Antarctic Circle, which is about 66.5 degrees south latitude. This means that during the summer solstice in the Southern Hemisphere, the sun will still be lower in the sky at noon for locations south of the Antarctic Circle.

When was A Sun That Never Sets created?

A Sun That Never Sets was created on 2001-08-07.

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.

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.

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 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.

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

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 direct the coarse adjustment knob on high power?

Well, friend, using the coarse adjustment knob on high power can damage both the microscope and your slide. It's like trying to paint a delicate flower with a big brush - you need a gentle touch for the best results. Take your time, use the fine adjustment knob, and you'll see the beauty of your specimen clearly and without harm.
