10 X 10 = 100 magnification.
Ocular lens = 10
Objective lens = 10

How you find the magnification of a microscope?
Simply, multiply the magnification of the ocular lens times the magnification of the objective lens you have in place.
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.
Microscope problem only half the field is illuminated?
If only half your viewing field is lit, twist objective lenses until they click into place.
What is the difference between binoculars and microscope and telescope?
Ha! This is a subtle matter. Both magnify. A microscope magnifies something close to you, while a telescope magnifies something far away. But let's look deeper. Both telescope and microscope have an objective lens that projects an image called a real image. The eyepiece is used to further magnify a portion of the real image. The objective lens of a microscope is designed to produce a real image of something that is close to the lens, and the real image will be larger than the object you are looking at. Suppose it makes an image 10x larger. Then the eyepiece adds magnification. An eyepiece that by itself can magnify something 15x, when used to look at the image from a 10x objective, produces a total magnification of 150x. The objective lens of a telescope is designed to produce a real image of something that is at a much larger distance, and the real image will usually be smaller than the object (usually much, much smaller!). The longer the focal length of the objective, the larger the real image will be. Then it is the ratio between the focal length of the objective and the focal length of the eyepiece that determines the visual magnification. For example, may amateur telescopes use an objective lens or mirror (or some combination) that has a focal length of one meter, or 1000 mm (~40 inches). A common eyepiece focal length is 20 mm (~0.8 inch). 1000/20 = 50x. Large professional telescopes are typically never used for visual observing, but on rare occasions the 200 inch (5 m) Palomar telescope was used visually in the past. Its 55 foot focal length (16.75 m) when used with a 20 mm eyepiece would produce nearly 840x magnification. Both telescopes and microscopes can be used for photography by either putting the film or digital imaging sensor where the real image is in focus on it, or by using a special eyepiece to project an enlarged real image further back, where it might be more convenient to place the camera back with its lens removed.
What are the two basic principles involved in using a microscope?
principle of microscopy includes 2 important aspects: 1. resolution and resolving power- the resolving power of a microscope is defined as the minimum distance by which 2 points must be separated in order for them to be perceived as 2 separate points rather than a fused image. 2. magnification- Linear (sometimes called lateral or transverse) magnification refers to the ratio of image length to object length measured in planes that are perpendicular to the optical axis. A negative value of linear magnification denotes an inverted image. Longitudinal magnification denotes the factor by which an image increases in size, as measured along the optical axis.
How you find the magnification of a microscope?
Simply, multiply the magnification of the ocular lens times the magnification of the objective lens you have in place.
A microscope should be stored with the objective in place?
It should be stored with the low-power objective in place.
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.
Which objective should be in place both when beginning to use the microscope?
Scanning objective
What does total power of magnification mean?
The total power of magnification refers to how many times bigger than actual size you are viewing the specimen with a microscope. It is measure by multiplying the magnification of the eye piece by the magnification of the objective lens you are using. For example, most eye pieces magnify by 10X. So, if you are viewing a specimen with the 4X objective lens, you are actually seeing the specimen 40 times larger than normal. (10X * 4X)
What holds the objective on a microscope and turns them into place?
the nosepeice. it may have other names but this is what i know it as.
What power must be in place when you first find an image on a microscope?
idk
Where are your eyes when changing the magnification?
You should be watching the objective lens move into place to make sure that it is not going to hit the slide.
Why is it not safe to remove slides from the microscope when 100x object is in place?
Because the objective touches the lens.
Working principle of microscope?
microscope consists of two lens called eye lens and objective lens. objective lens is lens kept behind object and eye lens is keep on the top of microscope .i.e. on the place through which we look. firstly the object is placed behind the objective of microscope which is turned into virtual, erect and magnified image. later this image is thought to be the object for the eye lens and this objects forms real, inverted and magnified image.
Microscope problem only half the field is illuminated?
If only half your viewing field is lit, twist objective lenses until they click into place.
What is one advantage of using the dissecting microscope instead of a compound light microscope?
A dissecting microscope has a lower magnification than a compound microscope. A dissecting microscope has a bigger work area so you can use it to magnify and still move around what ever your looking at. A compound microscope would be used to look at cells that you could not see with out intense magnification You would have to use a microscope slide for whatever you wanted to look at. Example: A dissecting microscope would be used to figure out the sex of Fruit flys. While a compound would be used if wanted to see the cells of a the fly's eye
