Why must initial focusing of an object be under the low power objective and not under the high power objective?

Low power objective is like our eye if we want to see we can just see normally but if we want to see something very small but want to see properly at that particular part then we always go for some lens of something powerful. That's the same thing when we want to know something deeply we go for high power microscope to read a more detailed study of a particular part of object under the microscope.

How much larger than normal does an object appear with a low-power objective?
how much larger than normal does an object appear with lower power objective?
When focusing a specimen you should always start with which objective?
Ocular Lens (eyepiece) or Stage
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.
Describe how to relocate an object that is lost while viewing high powered objective?
The best way to relocate a lost object when using a high-power microscope is to raise the body tube, check the slide to make sure the object is still on it, and adjust the light source if necessary. Then, starting with the coarse adjustment knob start focusing on the object again.
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.

What is the use of the coarse adjustment knob?
The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.
What is object environmentalism?
objective environmentalism is the power of people in which you are organized by them

What is the BEST procedure for focusing a compound light microscope?
Begin by using the lowest power objective lens and then switching to the next highest power lens.
How much larger than normal does an object appear with a low - power objective?
how much larger than normal does an object appear with lower power objective?
Why is locating an object more difficult if you start with the high-power objective rather than the low-power objective?
With a high power objective you see less sky and might not know where you are looking. With a low power objective you see more and it is possible to orient yourself among the objects in view.

What is the effect of changing from lower power objectives to higher power objectives?
Low power objective magnifies the object by 10 times, whereas high power objective magnifies 40 times. When we change from low power to high power, the object appears larger, exactly 4 times larger than low power. Low power objective covers a larger area, whereas high power covers a smaller area.
What is found on the nosepiece of a microscope that ranges from high to low power?
The objective lens is found on the nosepiece of a microscope that ranges from high to low power. It is the lens closest to the object being examined.
