Best Answer

MP=(d/L)*(1-(L-l)f)

where d would be the distance from the eye to the image without a lens

L is the distance from the eye to the new virtual image (with a lens)

l is the distance from the eye to the lens

this equation only covers a single lens (whereas there tend to be two in a microscope), but that's no worry; use it twice!

(i.e treat both lenses as independent sources of the image)

You multiply the eyepiece magnification by the objective magnification.

For example if the eyepiece magnification is 10X and the objective magnification is 40X the total magnification would be 10 X 40 = 400X

It will tell you on the rotating lens. Usually 4x, 10x, 40x on an electron microscope plus 10x for the ocular lens. (eyepiece.) So if you have 10x and the eyepiece is 10x, then the total magnification is 100x.

When using a common light microscope - simply multiply the eyepiece magnification and the objective magnification.

For example, if the eyepiece magnification is 10X and the objective magnification is 40X, the total magnification will be 10 X 40 = 400X.

To determine the total magnification of a microscope you multiply the magnification power of the objectives lens (indicated as x10) by that of the eye piece.

take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.

You can multiply the power of the lens by the magnification you are using.

Ex. Power of lens 10x, power of magnification 40x

Total magnification 400x

Would a compound light microscope and dissecting microscope be used in the same lab situation?

Yes, it could. If one is working in a lab for the health department for example, both would be useful. One might have a sample and would use the low magnifying dissecting scope to find something of interest and then the compound 'scope for more detail of the it.

What are the reasons for always starting on low power for microscope?

The higher the power, the more difficult it is to have the item being viewed centered in the viewing field. However at lower power the viewing angle is wider and it is easier to find and position the item in the field. So we start by centering the item in the field at lower power, increase the power and center it again.


Why is slide centered before moving to higher power on microscope?

When you switch to high power, you are focusing on a very small part of the large picture. If you center your object under low power (preferably by the little black arrow most microscopes have) you will see the object you are looking at 100% of the time. If you do not center your object, the object will end up being off to the side of what you are looking at in your field of view. It's kind of like zooming in on a map on the internet, you have to center what you want to zoom in on or else you will zoom in on an area you did not want to look at.

What power must be in place when you first find an image in the microscope?

You should first use the lowest power setting of a microscope to find an object and then center it within the viewing area. Then, when you switch to the next higher magnification, your target should still be close to the center and easier to find and focus on.


Can you see molecules with a maginfy glass or a microscope?

A magnifying glass is not powerful enough to see molecules. You would need a very high powered microscope to see molecules and it's not likely something you will find in just any science lab.


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.

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.
