In relation to a microscopewhat is magnification and resolution?
Magnification is the amount by which the image you see will be larger than the actual object, ie. if the image you see appears to be twice as large as the original object then it will be a 2x magnification. (magnification = size of image / size of object) Resolution is the smallest possible visible thing on the enlarged image. On a satellite picture the resolution may be 1m2 meaning that anything smaller is not visible on that picture. In the case of an electron microscope, for example, anything smaller than 1 electron will not be visible using the electron microscope.
Can you see a bacterium that is 1 micrometer in size?
You cannot see microbes with the naked eye, hence their name. To see them requires magnification such as a microscope.
Compare and contrast a compound light microscope and an electron microscope?
Light microscope: 1. Uses a beam of light that is focused using glass lenses. 2. Magnification is moderate -- not as much as electron microscope 3. Produces a color image since it uses light 4. Can look directly at the specimen with our eyes Electron microscope 1. Uses a beam of electrons that is focused using magnets. 2. Magnification can be extremely high and show details that are not possible with the light microscope 3. Produces a grey-scale image because color requires visible light 4. Image must be seen on a monitor or in a photograph because we don't see electrons.
How do microscopes differ magnification and resolution?
Before we analyze exactly how microscopes differ magnification and resolution is it important to know the difference between the two. When we talk about a microscopes magnification it is a reference to how much the microscope can enlarge an image. However, when one refers to a microscopes resolution it is the ability for the microscope to produce a sharper and more clear image. Thus, resolution is the ability to tell two points apart from each other. For instance, imagine we place a small cell under a microscope. If the cell is very large it has a large magnification but that does not mean that it has a good resolution; the cell may appear fuzzy. However, by tweaking the resolution the cell can come into full detail and may be examined. Magnification is usually described as 10x or 100x, which means 10 times or 100 times the size. Resolution can be described as any unit of measure. For instance, if your microscope can make a distinction between two points that are 1 micrometer away from each other the resolution can be said to be 1 micrometer.
If car 1 has a greater inertia than car 2 then car 1 has?
has a greater mass than car 2
Does a microscope have more than 1 lens?
Yes they can have different magnification.
How many lenss are in a compound light microscope what is the function of the lenss?
The simplest optical microscope is the magnifying glass and is good to about ten times (10X) magnification. The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object.
Which microscope has the greatest magnification transmission microscope or scanning microscope?
transmission microscopes. they can magnify an object 1 million times.
What is the total magnification of a microscope if the microscope is on high-power?
This depend on type of microscope and in particular which specific model it is. High power may refer to the microscopes ability to enlarge a lot, not that it actually consumes power. In this understanding of the term, the microscope in question might have two separate but combined lenses of which the total magnification can be calculated from. It may have an objective lens and an eye piece lens, both of which that might be changed in order to achieve greater or less magnification. Typical configurations are: Objective lenses of 1, 2, 3, 4, 10, 40, 100X magnification Eye piece lenses of 5, 10, 15, 20X magnification. If your microscope fits this configuration, then the maximum magnification you can achieve is 100x20, a magnification of maximum 2000 times. The problem here is the wavelength of visible light. It does not allow for more magnification than approx 1500 times and even this is not a very detailed one.

What limits the useful magnification of a compound microscope?
Several things do: 1) what magnification the ocular is (usually 10x) and the highest magnification of the objectives (usually 100x), giving you a total mag of 1000x 2) resolution, which in turn is affected by numerical aperture

What are the powers of the objective lens in the microscope?
The function of the lenses of a compound microscope is that they help you see better and more detailed at the object. And also, the field of view is ten times greater than the magnification so you can see even better.
List three differences between the dissecting microscope and the compound microscope?
1. compound microscope has higher magnification power 2. Dissecting is used for studying 'big' objects 3. compound is for looking at cells, etc.
What is the highest TEM magnification?
Up to about 750,000 times. Strictly, it is not magnification that matters with any microscope. There is no practical value in enlarging an image if the enlargement reveals no further detail, but just makes the blur bigger!The critical factor is resolution, which is a measure of the detail that can be discerned in the image. A transmission electron microscope (TEM) has, at best, a resolution of about 1 nm, which means that objects closer than 1 nanometer apart cannot be distinguished. This is about 100 times the best resolution available using a light microscope.
What is meant by magnification is greater than 1?
its nothing it means that the type of mirror you are using is canvex that forms a virtual image and has a power in negative . i think you got it now !
What are two advantages of the electron microscope to the light microscope?
The two big advantages are: 1. Magnification: the electron microscope can be used to visualize individual molecules and even atoms! 2. Resolution: The ability of a microscope to distinguish two closely lying points as separate entities.
