I assume this is a question about viewing an object through a compound microscope. Always use the shortest objective lens (that is the one with the lowest magnification) first. Focus the lens and then when you want more detail or a closer view, you can simply rotate the lens turret to a longer lens and it should be nearly in focus. Use the fine focus feature to sharpen the picture. If an object is viewed in this way, the danger of scratching the high power objective by ramming it into the slide is lessened.

Why should you use the scanning objective to find objects first?

What is the large knob on the side of a microscope that should be used first when viewing a slide?
This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.
What is the name often given to the force exerted by the second object back on the first object?
As the designation 'first' and 'second' (in this case) is purely objective (assigned by the viewer) there is no special terminology applied as both forces are exactly the same force and are known by exactly the same terms:gravitationalelectrostaticweak-nuclearstrong nuclearmagnetic
What does the coarse-adjustment knob off of a microscope do?
It is the first knob you should turn to bring the object into rough focus, before tinkering with the finer tuning knobs.
Why should you always view a slide at a power first?
When viewing specimens or objects under a microscope, it should be set to a low power first. This allows for a wider field of view that makes an object easier to locate.
What are the magnifications on the objective lenses?
There are many different microscopes currently on the market. Most of these microscopes come with different levels of magnification so that you can view an object in different ways. It is important to make sure the microscope you choose to use will have the correct maginfication you need.
Should I use either you or I have to attend the meeting or either you or me have to attend the meeting?

What kind of pronoun case is me?
The pronoun "me" is in the objective case. It is used as the object of a verb or a preposition.
Why should you always view a slide at low power?
When viewing specimens or objects under a microscope, it should be set to a low power first. This allows for a wider field of view that makes an object easier to locate.
What was the main object of the first crusade?
The main objective was to spread Christianity and try to take back the Holy Lands( Jerusalem). They had 8 crusades and all of them had about the same military objective as the first one.
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.
Why Low power objective before High Power objective?
The low power objective is used first for two reasons: First, focusing the low power objective will insure that the other objectives will be at the proper height. Smashing a slide with an objective can damage the objective. Second, you can see a greater area with the low powered objective. This allows you to easily locate an object of interest, center it in frame and then zoom in on it.
