Why shouldn't you use the course adjustment knob when viewing the specimen under high power?
You shouldn't. You can cause the high objective to smash into the surface of the slide and crack it. Always use the fine adj. for high power and if you cannot get the high power in focus, reverse out to low again and do it over. Ideally, if you are in focus on low, you should be in focus at medium (may have to adjust a small amount) and if you are in focus under medium, when you swing the high power obj. into place, it should be in focus as well (may need a fine tune). Always reverse out and start all over again if you cannot focus it under high power. Deja Was Here
Can all threads be in focus again using the high-power objective if a certain thread is focused using control knob?
All the threads can be in focus again using the high-power objective if a certain thread is focused using the control knob to make adjustments. The knob allows for very small changes to be made which will create a precise focus.
When do you use high power objective lens?
The primary rule to apply when using the high power objective is to always stay focused. By doing this, a person or team will be able to reach their goal much easier.
What the low power objective in animal cell?
power objective
Why would you always use the low-power objective lens to locate objects mounted on the slide first even if you want to observe them with the high power objective lens?
because it allows you to find the part of the slide you want to see, then you can zoom in by changing focus to see the frame in greater detail. if you don't start in low power it is extremely difficult to move around the slide
Why important to start focusing the lowest power objective?
You use the low power objective lens first to get your sample centered in the field of view.
What is used to focus when using the scanner and low objective?
The coarse and fine adjustment knobs can be used with the low power objective.
What are the steps used to focus a microscope on high power?
First focus the microscope on the lowest objective using first the coarse djustment knob and then the fine adjustment knob. Once you have it in focus, move on and do the same for the next highest objective. Continue this process until you reach the highest objective and focus it in the same fashion.

What is the power of the low power objective lens?
The low power objective lens helps to first fine the specimen or object being viewed, and to focus the microscope. Once the lens power becomes higher it is much harder to focus the microscope and find the desired object of viewing.
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.
When focusing a specimen you should always start with which objective?
Ocular Lens (eyepiece) or Stage
Can all threads be in focus again using the high-power objective if a certain thread is focused using control knob?
All the threads can be in focus again using the high-power objective if a certain thread is focused using the control knob to make adjustments. The knob allows for very small changes to be made which will create a precise focus.
What is the objective lens used to locate the specimen and the first focus?
When viewing a specimen, you must always use the lower power objective lenses first. Low power lens gives the widest field of view and makes it easier to find the specimen when you look through the microscope. Finding the specimen at high power, without first centering it in the field of view at low power, is nearly impossible.
Why should you always begin to a microscope with the low-power objective?
because it allows you to find the part of the slide you want to see, then you can zoom in by changing focus to see the frame in greater detail. if you don't start in low power it is extremely difficult to move around the slide

Why the specimen must be centered in the field of view on low-power before going on to high-power?
Because it is too hard to find a specimen on high power. Easier to find them and focus them on low power and then increase the magnification and fine-tune the focus to get a better, closer look.
