A sample should be examined with low power first when observing any sample for the first time under the microscope. Now if you want to focus on one particular region in the sample then you can step it up to high power lens. Objective lens are not that expensive and good way to look at some simple tissue structures.

Which objective lens should always be in place when beginning to use the microscope and when putting it away?
The objective lens with the lowest magnification, usually 4x. Be sure to clean all the lens with lens paper before putting the microscope away.
Why do you use on or slide to be examined with the oil immersion objective?
If you are using the oil immersion objective on a microscope, you must use oil to increase the resolution of the lens. These lens are used at very high magnification.
What should be turned to click the scanning objective lens into place?
b
Is the low power objective lens the shortest objective lens?
scanning objective
If the total power of magnification is 400x and the eyepiece is 10x what is the objective lens power?
One can obtain a total magnification of 400x while using an objective lens of 40x. Such a lens should be used along an eyepiece of 10x.
What objective lens is it easiest to find or locate your specimen?
You should use the lowest value lens. It is the shortest one.
Why a microscope should be stored in low power objective lens?
A microscope should be stored in low power objective lens because the lens can scratch against the lens.
Which objective lens should you begin with?
The low power or lowest power objective
What is ocular lens and objective lens?
The ocular is the upper lens and objective is the lower lens
What is a objective lens?
low power objective lens
Why is it important to use the fine adjustment knob when using the highest power objective lens?
So you do not crack the high power objective lens - this lens is very fragile and expensive.
Which objective lens should always be in place when beginning to use the microscope and when putting it away?
The objective lens with the lowest magnification, usually 4x. Be sure to clean all the lens with lens paper before putting the microscope away.
Why should you use fine adjust when the high power objective is in position?
So you don't crack the slide or damage the lens
What does the objective lens in a microscope do?
The objective lens in a microscope helps to magnify the object being viewed on the slide. The objective lens can be rotated to change the magnification of the lens and yield a different view.
What objective lens is the longest?
The lens with the greatest (positive) curvature. The lens with the highest diopter.
Why should you look to the slide before you lower the objective of your microscope?
so the objective lens will not touch the slide.
Which objective focuses closest to the slide when it is in focus?
The objective lens that focuses closest to the slide is 100x, it has the longest lens so the highest power. Be careful not to crack the slide and make sure you use oil if it is an oil immersion lens.
