What type of image is formed by a mirror if m 5.2?
If the magnification factor (m) is positive (greater than 1), then the image is upright and enlarged. If the magnification factor is negative (less than -1), then the image is upright and reduced. If the magnification factor is between -1 and 1 (excluding 0), then the image is smaller and inverted.
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.
What is the difference between compound microscope and an electron microscope?
A compound microscope is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope. An electron microscope is a type of microscope that uses a beam of electrons to illuminate the specimen and produce a magnified image. Electron microscopes (EM) have a greater resolving power than a light-powered optical microscope, because electrons have wavelengths about 100,000 times shorter than visible light (photons), and can achieve better than 50 pm resolution[1] and magnifications of up to about 10,000,000x, whereas ordinary, non-confocal light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x.
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.
What can be seen under a electron microscope but not a light microscope?
You can see a hair fiber well using an optical microscope, but you can hardly see a dimension 100 times smaller (about 10 microns). An electron microscope can review features as small as 10 nm, about 1/100000 th of a fiber.
Which microscope has the greatest magnification transmission microscope or scanning microscope?
Transmission electron microscopes (TEM) generally have greater magnification than scanning electron microscopes (SEM). TEM can achieve magnifications up to 1,000,000x, while SEM typically reaches up to 100,000x.
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.
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 type of image is formed by a mirror if m 5.2?
If the magnification factor (m) is positive (greater than 1), then the image is upright and enlarged. If the magnification factor is negative (less than -1), then the image is upright and reduced. If the magnification factor is between -1 and 1 (excluding 0), then the image is smaller and inverted.
List three differences between the dissecting microscope and the compound microscope?
The dissecting microscope has a lower magnification range (up to 40x) compared to the compound microscope, which can go up to 1000x. The dissecting microscope has a larger working distance and a wider field of view, making it suitable for observing larger specimens. The dissecting microscope typically has a lower resolution than the compound microscope due to its lower magnification power and optical design.

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.
Does a microscope have more than 1 lens?
Yes, a compound microscope has more than one lens. It typically has two lenses: the objective lens and the eyepiece lens. The objective lens magnifies the specimen, while the eyepiece lens further magnifies the image for viewing.

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 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 !
