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.
What else can I help you with?
A magnification of 100 requires the use of what objective?
A magnification of 100x typically requires the use of a 100x objective lens on a microscope. Different microscopes may have varying objective lens magnifications, but for a total magnification of 100x, the 100x objective is commonly used.
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.
When beginning to focus a microscope what lens should you use?
You should start by using the lowest power objective lens, usually the 4x or 10x objective, to locate and center the specimen on the slide. Once the specimen is in focus, you can switch to higher magnifications for more detailed viewing.
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.
Is the low power objective lens the shortest objective lens?
scanning objective
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 should you only use the fine adjustment knob when you are using high power?
The fine adjustment knob should be used with high power magnification because it allows for smaller, more precise movements of the objective lens. This helps to prevent damage to the slide and objective lens, as well as minimize the risk of crashing the objective lens into the slide.
A total magnification of 100x requires the use of the 10x ocular lens with which objective?
To achieve a total magnification of 100x, you would use a 10x ocular lens (eyepiece) with a 10x objective lens. The total magnification is calculated by multiplying the magnification of the ocular lens (10x) by the magnification of the objective lens (10x).
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 a microscope should be stored in low power objective lens?
Storing a microscope with the low power objective lens in place helps protect the lens and prevents accidental damage or contamination during storage. The low power lens is less delicate compared to other high-power lenses, making it a safer option for storage to ensure the microscope remains in good condition for future use.
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.
A magnification of 100 requires the use of what objective?
A magnification of 100x typically requires the use of a 100x objective lens on a microscope. Different microscopes may have varying objective lens magnifications, but for a total magnification of 100x, the 100x objective is commonly used.
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 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 look to the slide before you lower the objective of your microscope?
so the objective lens will not touch the slide.
When storing a microscope which objective lens should be pointed downward?
10x
