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
Electron microscope would be used if?
Electron microscope would be used if higher magnification and resolution are required to visualize objects at the nanometer scale. It is suitable for studying the ultrastructure of cells, tissues, and materials with high detail and clarity.
Which type of microscope can observe non-living cells?
A tunneling electron microscope cannot image live specimens.
What Microscope that gives 3-D image?
There are at least two types of microscope that can give 3D images. Confocal microscopes that use lasers to illuminate the object and scanning electron microcopes (SEM) that use an electron beam. A SEM can give better magnification than confocal but confocal can image live moving subjects. In SEM the object of intrest must be coated with gold so only dead things can be imaged.
One limitation of the scanning electron microscope is that it cannot be used to?
One limitation of the scanning electron microscope is that it cannot be used to observe live samples or biological materials in their natural state. The high vacuum environment and the electron beam can damage or alter the sample.
When is it better to use a light microscope rather than an electron microscope?
When you need to observe a live specimen
Can the light microscope be used to study a live specimen?
Yes, light microscopes can be used to study live specimens. Special techniques such as keeping the specimen under controlled conditions (like temperature and humidity) and using a coverslip to prevent drying can allow for observation of live processes such as cell division or movement.
What is the difference between ordinary microscope and electron microscope?
Magnification and resolution is in light microscope is about 500x and 0.2micro metres respectively than human eye.In e.microscope magnification is about 200,000x and resolution is 0.0005micro metres. You cannot observe live specimen through electron microscope. Lenses in light microscope are glass while e.microscope use magnetic lenses. E.microscope is relatively very larger than light microscope. You need special knowledge to handle electron microscope. You can observe through naked eye in e.microscope. A beam of electrons is sent through specimen in e.microscope.In light microscope a beam of light is sent. Electron microscope is very complex relative to light microscope.

How would you distinguish between the light microscope and the electron microscope?
A light microscope uses visible light to magnify the specimen, allowing for observation of living cells and tissues. In contrast, an electron microscope uses a beam of electrons to achieve higher resolution and magnification, enabling visualization of smaller structures such as viruses and molecules.
Electron microscope would be used if?
Electron microscope would be used if higher magnification and resolution are required to visualize objects at the nanometer scale. It is suitable for studying the ultrastructure of cells, tissues, and materials with high detail and clarity.
Which type of microscope can observe non-living cells?
A tunneling electron microscope cannot image live specimens.
What kind of microscope is used to view living specimens?
a TEM (transmission Electron Microscope) shoots electrons through the specimen and shows internal features of the cella SEM (scanning electron microscope) Electrons bounce off of the surface of the specimen, and show a 3d image of the surface on the specimen.a STEM (scanning tunneling electron microscope) uses a needle like probe shoots electrons from the inside out, shows 3D surface image CAN be used on living specimens
What type of microscope would you use to view a sample of live microorganism in pond water?
You would use a compound light microscope to view live microorganisms in pond water. This type of microscope uses visible light to illuminate and magnify the specimen, allowing you to observe living organisms in real time.
What are the advantages of an electron microscope over a light microscope?
An electron microscope can reach a far greater magnifiction than a conventional microscope. It is obvious that the largest advantage of any type of microscope is to observe an organism that can not be seen by the unaided eye. Light microscopes are easy to use, can magnify up to 2000 times, enable magnification of live cells and their movement, and are relatively cheap compared to electron microscopes. The only disadvantage is that it can only magnify up to 1000 times, after that the image is blurry, whereas an electron microscope can magnify up to 100,000 times! However, electron microscopes are extremely expensive, difficult to use, and cannot observe live specimens.
What Microscope that gives 3-D image?
There are at least two types of microscope that can give 3D images. Confocal microscopes that use lasers to illuminate the object and scanning electron microcopes (SEM) that use an electron beam. A SEM can give better magnification than confocal but confocal can image live moving subjects. In SEM the object of intrest must be coated with gold so only dead things can be imaged.
Can live specimens be used in a TEM microscope?
Live specimens cannot be used in a transmission electron microscope (TEM) as the high vacuum environment and electron beam would quickly kill any living cells. Instead, biological specimens must be fixed, dehydrated, and stained prior to imaging in a TEM.
