A phase microscope is also called a phase-contrast microscope or a phase-difference microscope. A phase microscope allows better viewing of clear specimens which usually need to be stained before you can make out the various parts. Staining is a time consuming process and kills the cells being...
Anton Van was the first man to witness a lve cell under a microscope.
Everything under a microscope is upside down and backwards.
because cells are too small to see with the naked eye. if you get a microscope, you can see them. seeing=believing. so, theory proved.

That depends on the type of microscope you are using, so check the lab you work or go to school in. At my lab, our microscopes have 4x, 10x, 40x, 100x magnification lenses.
It separates the objective lens from the eyepiece (occular lens) and keeps out ambient light.
Microscopes cannot view viruses as viruses are smaller than the wavelength of visible light (about 0.2 microns). To view extremely tiny objects, scientists use electron microscopes. Electron microscopes use electron beams instead of light to magnify objects less than 1nm!
You don't want yucky stuff mushing itself onto your objective lens. Slide covers save you from constantly cleaning your lens.
  Electron microscope uses tiny particales of matter called electrons,to produce magnified images.
The letter 'e' is inverted upside down (180 degrees) and inversed or reflected by 180 degrees
the compound micro and the electron one will win since they are both double and triple the simple one because of the technology which increases
if you're just using it(in the middle of looking into somthing). make sure nothing is around the table which can make the scope fall
For an optical microscope, the principle of refraction, in its lenses.
Telescopes and microscopes both enlarge objects so that more detail can be seen.
Not all, but microbiology techs certainly do.

  To illuminate the specimen.
Answer by NO.1GreatThinker :- The basic purpose of the negative staining experiment is to check out the bacteria / micro-organisms which have less amount of peptidoglycans present in their cell wall So experiment can be performed to distinguish gram negative bacteria from gram positive one . It...
A convex lens bends the light that goes through it toward a focal point. The light spreads out again past this focal point. Magnifying glasses are convex lenses. When you use one, the lens bends the light rays so that they come together and focus on the lens within your eye. The light then spreads...
Because they allow you to see minute things. some amplify 1000000 times!
A phase-difference microscope (or phase-contrast microscope or phase microscope) allows better viewing of clear specimens that usually need to be stained before you can make out the various parts. Staining is a time consuming process and kills the cells being viewed. With a phase-difference...
It makes the substance you're looking at clear, and not blurry.It basically puts it into focus.
That will vary on what country you reside. In the United States you will find a microscope set at a major outlet like ToysRus. Expect to have a pretty basic microscope.   If you are more serious, check with local medical supply stores for your area. High schools' science teachers/labs could give...
Scientists never have, nor will they ever, actually know what an atom looks like. Scientists today still measure the properties of atoms via indirect methods, similarly to how they used to, the only thing that's changed is the precision of the measurements. When you look at a picture from an...
those two things are important because the cells are very small and  you need those things to see the better
An optical microscope uses a system of (usually) glass lenses to focus the small amounts of light given off by the subject into your eye.
it protects the body of the microscopes
The electron microscope can magnify by a larger factor than an optical microscope can, thereby enabling us to see even smaller objects.
Electron microscopes are more powerful.
Yes. The optical microscope is the original light microscope.
Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.
They enlarge and put into focus the object on the slide.

Microscopes are used to see objects too small for the human eye.One of the first microscopes was made in 1590 by Zaccharias and Hans Janssen.Galileo later improved their invention in 1609.Three types of microscope:-Optical (uses visible light wavelengths)-Electron (uses electrons to magnify the...
a simple microscope only have one lens but a compound microscope have two or more lens
No it doesn't , but you can make 3d image by taking three or four 2D scans of titled sample and then using image processing reconstruct it in 3-D
mixtures with different parts that can be plainly seen with the  naked eye but speckled under a microscope are called ?
Zeiss was active in improving the design and manufacture of  microscopes, in advancing the theory of lenses and in creating new  types of lens glasses. For more about him you might see his  wikipedia article.
Many careers involve the use of microscope. To name few biochemists, biologists, and in forensics. Anything that may require studying at cellular, molecular or atomic level requires the use of a microscope. Many people use it to simply appreciate the structure of items which are too small to clearly...
In about 1595, Zacharias Jansenn built the first microscope. Sometime about the year 1590, two Dutch spectacle makers, Zaccharias Janssen and his father Hans started experimenting with these lenses. They put several lenses in a tube and made a very important discovery. The object near the end of the...
the compound light microscope provided people the ability to see objects too small to see with the naked eye. It also enabled microscopes to magnify at different rates, usually 100x, 400x and 500x.
Viruses. They are smaller than the average wavelength of light and  as such are not viewable unless an electron microscope is used.
  The two main advantages of SEM over light microscopy is that the SEM has a much deeper depth of field and that it has higher resolution than a light microscope can achieve and the resultant much higher magnification from the SEM.
TEMs have a smallest resolvable separation distance (resolution) of about 0.5 nanometres, which is slightly above the atomic level of matter. By contrast, a light microscope has a resolution of up to 0.2 micrometres, and the human eye can see down to 100 micrometres.
An improvement in microscope increases its magnifying power by which the scientists can see cell's components clearly and their study becomes easier thus they can learn more.
1000x microbes are so tiny they need something to maximemise them alot
The best electron microscopes now can show us surfaces with individual atoms.This sort of technology will be invaluable when chemists start developing nano-scale engineering, allowing them to monitor the progress of the construction and visualise the function of these nano-machines.
the compound microscope allows for greater magnification than the dissecting microscope. Compound microscopes use a rotating nose with three different objective lenses offering different magnifications---typically up to 40x. The dissecting microscope has no rotating nose and offers magnification up...
1928 i believe by the Germans... someone check me on that... it wasnt the electron microscope we know today but it was the same concept only it magnified by a small 17 times... it has be improved since then
the first and foremost thing to know before you can use a microscope is how to use it?
they magnify the image of the cell, not the actual cell
Yes, but some microscopes are better than others.
The cells are Gram-Positive, Rod-Shaped (Bacillus).
Antonie van Leeuwenhoek was the first to see actual living things in water well over 300 years ago, in 1674. He saw moving animalcules or 'little animals' that were the algae Spirogyra and probably would also have seen bacteria in the sample. A few years earlier in 1665 Robert Hooke had seen under...
Microscopes give us the ability to view a cell at magnification that cannot be achieved by out naked eyes. With the help of standard microscopes we can enlarge the image of original specimen by 10-100 times more. With technological advancement we are now able to see cells with much larger...
The 'magnification' of the microscope is how far or close you zoom in to the picture. The larger the magnification, the closer you can see what you are looking at through the microscope.
were safety glasses and drop the slide
Carl Zeiss contributed to the first microscope by making the lenses better.
Bacteria that exists on your hands could contaminate whatever is on the slide, as well as preventing the oils on your hands from doing the same. Sterile forceps are therefore ideal to these ends. In addition, it allows you to lower the cover slip down with minimal disturbance to whatever is on the...
They have better resolution so the image they produce is more detailed and they can also be used to see internal details of cells. However the whole apparatus needs to be used in a vacuum so living organisms can't be observed.
I think that in most school microscopes, it is 10x
