If a light microscope has an eyepiece lens of magnification x15 what magnification of objective lens would be needed to get a total magnification of x1500?

The total magnification is equal to the magnification of the eyepiece multiplied by the magnification of the objective lens.
So in this case the objective lens would need to be 100X.

∙ 16y agoMagnification is calculated by multilplying the ocular lens by the objective lens. So, the total magnification would be 150x
Wiki User
∙ 14y agoTo find the total magnification, multiply the objective magnification by the ocular magnification. Therefore, 100*15=1500x

What are the names of some of the parts of a microscope?
There are many parts needed to make a microscope. Some of the parts of a microscope include the eyepiece lens, arm, base, tube, illuminator, objective lenses, diaphragm, and condenser lens.
As the magnification used in microscope increases is more or less illumination needed Explain your answer?
As the magnification increases, more light is needed. This is because the size of the hole of the lens is smaller.
Does resolving power increase with magnification?
If magnification increases ONLY, then resolving power does not increase. However, if the magnification increased while staying in focus (upgrading resolution and magnification with objective lense), shorter wavelengths are needed to stay in focus with increased magnification to yield the same high resolution as with previous objective lense, so this case, resolving power does increase.
Why is it one needs more illumination when using the higher levels of magnification?
It's actually simple: The more the magnification, the smaller a "picture" of the available light you are getting - hence the more magnification, the darker the image looks. It works the same way with an astronomical telescope: The more magnification you use (assuming the objective lens doesn't change) the dimmer the object gets. To put it another way - there is a big difference between how high a magnification you are using, and how much light is reaching your eye.
Why must you use a thin specimen when viewing with a light microscope?
For a light transmission microscope, a thin sample is needed in order for the light to pass through the sample from the light source on the other side. However, you can use a dissection microscope (another type of light microscope) which illuminates the sample from above, eliminating the need for a thin sample size. As the name suggests, this is normally used in dissections, and is of low magnification.
How much magnification does a eyepiece have?
The amount of magnification depends on the focal length of the eyepiece.

Does amount of light needed increase or decrease as one moves to higher magnification with the microscope?
The amount of light needed increases as one moves to higher magnification with the microscope. This is usually done by opening the light diaphragm.
As the magnification used in microscope increases is more or less illumination needed Explain your answer?
As the magnification increases, more light is needed. This is because the size of the hole of the lens is smaller.
How much magnification is needed to see a nanometer?
You cannot see down to the nanometer scale with light microscopes, you have to use something like a scanning tunneling microscope or an electron emission microscope. And since those don't use light I'm not sure you can really define the magnification.
What is the proper procedure for focusing the microscope?
start with the lowest objective then adjest your focus. After, switch your objective if needed going from lower to higher
Can the cell structures within a leaf be seen with a stereo microscope?
The cell structures within a leaf cannot be seen with a stereo microscope. A microscope that is equipped with transmitted light and also stronger magnification is needed in order to do so.
Why would a technician need to use a microscope with a high magnification?
It depends on what the specimen is. If for example - the specimen is a person's finger-print, then low magnification is sufficient. However - if the specimen is a sample of blood, a higher magnification would be needed to show individual blood cells.
Does resolving power increase with magnification?
If magnification increases ONLY, then resolving power does not increase. However, if the magnification increased while staying in focus (upgrading resolution and magnification with objective lense), shorter wavelengths are needed to stay in focus with increased magnification to yield the same high resolution as with previous objective lense, so this case, resolving power does increase.
When should the high power objective used?
A higher power objective lens in a microscope is used when greater magnification is needed to study an object. The higher power objective lens has a shorter focal length and needs to be closer to the object being studied. It has a smaller aperture (lens diameter) so it has a narrower field of vision and may require more light to be useful. This means that it is more difficult to find and center the item being studied under the lens and it is harder to focus the lens on the object.

What tool would you use to study the body parts of a spider?
For determining species and investigating all the fine features of spiders, it is often helpful and sometimes necessary to get magnification. Sometimes a hand magnifying glass will provide sufficient magnification. Sometimes an electron microscope is needed to see the finest structures.
