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 electron microscope over light microscope?
Electron microscopes offer much higher resolution and magnification capabilities compared to light microscopes. They allow for visualization of smaller structures and details, such as individual molecules, viruses, and cell organelles. Electron microscopes also have the ability to produce 3D images and can differentiate between materials based on their electron densities.
What are the advantages of an electron microscope over a light microscope - 46k?
Electron microscopes have much higher resolution compared to light microscopes, allowing for better visualization of smaller structures. Electron microscopes can also distinguish finer details due to the shorter wavelength of electrons. Additionally, electron microscopes can observe samples in greater depth by creating 3D images through techniques like tomography.
What do the scanning tunneling microscope and the one-angstrom microscope allow scientist to see?
The scanning tunneling microscope allows scientists to see individual atoms on a surface by detecting the tunneling current between the microscope tip and the sample. The one-angstrom microscope is a hypothetical concept that would potentially allow scientists to visualize atomic details with even higher resolution.
What would change about the way an electronscope worked if it's metal knob were replaced with a plastic knob?
Replacing the metal knob with a plastic knob on an electron microscope would not fundamentally change the way the microscope functions. The plastic knob may be lighter or less durable than the metal one, but it should still allow for fine adjustments and control of the microscope's settings.
The best way to understand the submicroscopic world is with?
The best way to understand the submicroscopic world is through tools such as electron microscopes and atomic force microscopes. These instruments allow scientists to visualize and study objects at the atomic and molecular levels, providing detailed insights into the submicroscopic world.
When biologists wish to study the internal structure of cells they use?
microscopes, such as light microscopes or electron microscopes. These tools allow scientists to visualize and analyze the different organelles and structures within cells at a high level of magnification. By using these techniques, biologists can gain insights into the internal workings of cells and better understand their functions.
What type of microscope would allow the viewer to see ribosomes inside a cell?
An electron microscope would allow the viewer to see ribosomes inside a cell. This type of microscope uses a beam of electrons to image the specimen at a very high resolution, enabling visualization of cellular structures like ribosomes.
What type of microscope would a biologist use to study the protein molecules on the surface of a cell?
A biologist would likely use an electron microscope, specifically a scanning electron microscope (SEM), to study the protein molecules on the surface of a cell. The high magnification and resolution of an SEM allow for detailed imaging of protein structures at the nanometer scale.
What microscope can observe a virus?
An electron microscope can observe viruses due to its high magnification capabilities that allow for visualizing extremely small structures like viruses, which are smaller than the wavelength of visible light. Transmission electron microscopes (TEM) and scanning electron microscopes (SEM) are commonly used types of electron microscopes for observing viruses.
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.
A group of scientists is studying the internal parts of a cell. Which microscope is most appropriate for these scientists to use?
An electron microscope would be most appropriate for studying the internal parts of a cell due to its high resolution and ability to visualize structures at the nanometer level. This would allow scientists to observe details such as organelles and cellular components in great detail.
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 can be seen under a electron microscope and not a light microscope?
An electron microscope has a much higher magnifying power and resolution than a regular light microscope. One can visualize molecules and even atoms using an electron microscope. This is not possible with a light microscope
What does the light microscope allow the scientist to view?
A light microscope allows scientists to view cells, tissues, and microorganisms at the cellular and subcellular level. This tool enables researchers to observe biological structures and processes in detail, aiding in their study of living organisms.
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 is the name of a structure a scientist builds to learn about cells and how they function?
A scientist would build a microscope to study cells and their functions. Microscopes allow scientists to observe and analyze cells at a microscopic level, helping them understand cell structure and behavior.
What are the Advantages of electron microscope over light microscope?
Electron microscopes offer much higher resolution and magnification capabilities compared to light microscopes. They allow for visualization of smaller structures and details, such as individual molecules, viruses, and cell organelles.
