Why should you always move the objective lens away from the slide when you're focusing a microscope?
If you move closer while looking thru the lens, there is a danger of cracking the slide, especially using coarse adjustment.
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.
What is rack stop of a microscope?
this is an adjustment that determine how close the objective lens can get to the slide.
What are the dangers of using the coarse-adjustment knob when focusing under high power?
It is possible to cause damage to the microscope or lenses when using the coarse focus- such as pushing the lens through the glass slide.
Why does a microscope slide need to be transparent?
So light can pass through the slide to the objective.
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 happens if you try to use the coarse adjustment when the 10x lens is in place?
One thing that can happen if you use the coarse adjustment while the oil immersion objective is in place is that the slide will end up breaking. It is better to use the fine adjustment.
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.
Which of the objectives comes closest to a specimen and is most likely to break a slide if proper precautions are not taken?
The high power objective lense will most likely break the slide. You need to use coarse adjustment on the low power objective lens.
Which of the objectives comes closest to specimen and is most likely to break a slide if proper precautions are not taken?
The high power objective lense will most likely break the slide. You need to use coarse adjustment on the low power objective lens.
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.
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.

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.

Which objective should the coarse focus knob be used?
The coarse adjustment knob is only used with the low-power objective lens (usually 4x) because all the other ones are too long and the coarse adjustment knob may bring the slide up too qucikly, therefore it might break the slide or crush the specimen being observed. When using the medium (10x) and high (40x) power objective lens, it is best to use the fine adjustment knob to focus on the details instead.
Why must the distance from slide to objective lens increase rather than decrease when coarse focusing with the scannin and low power objectives?
According to my neurons that the distance from slide to objective lens should be increase rather than decrease when coarse focusing with the scanner and LPO to obtain a clearer and more focus structure of a certain specimen.. U must ensure that the coarse adjustment knob is at it's extent and then turn on the fine adjustment knob clockwise for the easier visibility of the specimen =)) - VALERIC ACID ...sPCUTE ..=)
