1.in EM instead of ordinary light a particle beam of electrons is usedto illuminate the samle or the specimen.
2.it has a very good resolving power.
3.it used to examin very tiny particles such as viruses or virion which consists of RNA or DNA and a protein coat,also utilised in illustrating body cells and other micro-organisms.....thx......with best regards..

What are the advantages of an electron microscope over a light microscope - 46k?
An Electron microscope is more sophisticated. They use electrons and allow you to magnify objects up to 2000000x and view said objects in 3D.
What do the scanning tunneling microscope and the one-angstrom microscope allow scientist to see?
I think that it comfirmed the long held suspicion that you can see paterns in matter. I'm not sure what the tunneling microscope does.
What is the accuracy of a traveling microscope?
A traveling microscope is considered to be a low-powered microscope, however, it is powerful enough to allow for accurate size determinations. The resolution of the typical traveling microscope is 0.01 mm.
Why you coat the sample with a conductive material in a electron microscope?
Electron microscopes work by reflecting electrons from the sample to build an image. This achieves a higher degree of magnification than conventional microscopy which uses reflected photons (light) to build a magnified image. However, samples which are often viewed under an electron microscope (particularly biological samples) would not reflect the electrons by themselves, but would allow them to pass straight through. Coating the sample with a conductive metal ensures that the electrons are reflected by the coated sample so that a magnified image can be built up
What does a scanning tunneling microscope allow scientists to see?
The scanning tunneling microscope scans samples using a very fine metallic tip.
What type of microscope would allow the viewer to see ribosomes inside a cell?
Ribosomes are very small.So have to use an electron microscope.
What does the light microscope allow the scientist to view?
The light microscope allow the scientist to view the bloods in our body.
Why electron microscope cannot be used to study life processes?
because an electron microscope has a vaccum chamber which cannot allow oxygen to pass
Why might a microscopist who specializes in the use of microscopes to examine specimens use a light microscope instead of an electron microscope?
An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens.
What scientific tool do you use to observe organelles?
Either a light microscope or an electron microscope can allow you to observe cell organelles.
What are the advantages of an electron microscope over a light microscope - 46k?
An Electron microscope is more sophisticated. They use electrons and allow you to magnify objects up to 2000000x and view said objects in 3D.
Summarize information about electron microscopes using five or six bullet points?
1. electron microscope could magnify until 200,000 and have high resolution 2. they cannot be used on living organisms because it enters a vacuum so electron don't bounce off a gas molecule 3. it allow you to view molecule 4. electron microscope is a beam that hits a specimen and hitting back to draw the molecule in the fluorescent screen this is called transmission electron microscope 5. there is a scanning electron microscope that scans specimen coated by a thin layer of metal ions that bounce back forming 3-D image
What does an electron microscope allow scientists to do that they couldn't do with a light microscope?
Things To See Closer And Deeper Into The Thing They Are Looking At.
What do the scanning tunneling microscope and the one-angstrom microscope allow scientist to see?
I think that it comfirmed the long held suspicion that you can see paterns in matter. I'm not sure what the tunneling microscope does.
What is the difference between a light microscope and an electric microscope?
The difference between a light and electric microscope is that the light microscope is solar powered
Advantages and disadvantages of light microscope over electron microscope?
they are relatively smaller, electron ones are biggerthey are easy to usethey allow you to see coloured images, electron ones don'tyou can observe live specimen, specimen has to be dead with electron microscopesi was trying to view the answer in relation to transmmission
Which microscope magnification should be used to observe the largest field of view of an insect wing?
A dissection microscope would allow you to see the entire insect in a magnified fashion, but a light microscope or an electron microscope would both also work fine. Ultimately it would depend on how much detail you want to see.
