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 does the high lens of a microscope only use?
That is the oil lens. For suspension of microbes in an oil solution in which the objective lens is also immersed. Improves resolution.
When should you use objective lens?
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 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.
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 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.
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.
How does the procedure for using the microscope different under high power as oppose 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.

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
Which objective of a compound microscope would show the largest field of view?
You use the 3 objective lenses of a compound microscope to switch powers. There's LOW, MEDIUM, and HIGH power. With LOW power, you can magnify what you're looking at. With HIGH power, you can see things that you can't see with a naked eye.
Why should YOU Only use THE fine adjust when the high power objective IS in positions?
So you don't crack the slide or damage the lens
What is the lens that is used to find the specimen on a microscope?
You use the low power lens to find the specimen with a microscope. Once you have found the specimen on low power, you can switch to high power for greater magnification. Just be sure to use only the fine adjustment knobs for focusing on high power so the high power objective won't hit the slide.
When do you use the high power objective?
The high power objective on a microscope is used anytime you need to achieve greater detail and magnification, and is often used when identifying cells. The high power objective is generally not used in teaching/learning labs as it is usually an oil immersion lens. Using oil means greater cleaning & care is required.
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.
