Why is electron microscope used to view viruses?
Electron microscopes use a beam of electrons to visualize objects at a very high resolution, allowing scientists to see extremely small structures like viruses. The size of viruses is usually below the resolution limit of light microscopes, making electron microscopes essential for studying these tiny particles in detail.
Why is an electron microscope is used to see viruses?
An electron microscope is used to see viruses because viruses are much smaller than bacteria and cannot be seen with a light microscope. Electron microscopes use a beam of electrons to create a high-resolution image, allowing researchers to visualize viruses at the nanometer scale. This level of magnification is necessary to study the detailed structure and characteristics of viruses.
Which microscope is use to study internal parts of a cell?
An electron microscope is typically used to study the internal parts of a cell because of its high resolution and magnification capabilities. Transmission electron microscopes (TEMs) and scanning electron microscopes (SEMs) are commonly employed for this purpose.
What do scanning electron microscopes and transmission electron microscopes have in common?
Scanning electron microscopes and transmission electron microscopes are both types of electron microscopes that use beams of electrons to create detailed images of tiny objects at a very high magnification.
What type of microscope are used to study cells?
Biologists typically use light microscopes to study cells. These microscopes use visible light to illuminate the sample and produce magnified images of cells. Other types of microscopes, such as electron microscopes, can also be used to study cells at higher magnifications and more detailed levels.
What the microscope can not do?
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!

What are the different types of microscopes and how are they used in various fields of study?
There are several types of microscopes, including light microscopes, electron microscopes, and scanning probe microscopes. Light microscopes use visible light to magnify objects, while electron microscopes use beams of electrons for higher magnification. Scanning probe microscopes use a physical probe to scan surfaces at the atomic level. These microscopes are used in fields such as biology, chemistry, physics, and materials science to study objects at a microscopic level and understand their structure and properties.

What types of objects can be studied with a light microscopes. what types can be studied with an electron microscopes?
Light microscopes are used to study living organism and to watch and analyze their structures. Electron microscopes use a dead specimen and are able to observe structures in great detail and with much much higher magnification. +++The electron microscope has a far higher definition and magnification than an optical microscope could achieve, but as you say you could not use it to study a living organism.
Why are we not able to see viruses with the compound light microscopes we use in the science lab?
Viruses are much smaller than the resolving power of compound light microscopes, which are limited to about 200 nanometers. Most viruses are smaller than this limit, requiring electron microscopes that have much higher resolving power to visualize them.
What type of microscope are used to study cells?
Biologists typically use light microscopes to study cells. These microscopes use visible light to illuminate the sample and produce magnified images of cells. Other types of microscopes, such as electron microscopes, can also be used to study cells at higher magnifications and more detailed levels.
What kind of microscopes use beams of electrons to produce magnified images?
Electron microscopes use beams of electrons to produce magnified images. There are two main types: transmission electron microscopes (TEM) and scanning electron microscopes (SEM). They are capable of achieving much higher magnifications and resolutions compared to light microscopes.
How does the electron microscope permit scientists to see viruses?
Viruses are very small and can be considered ultramicroscopic. We were not able to see them with the best light microscopes as we could bacteria (prokaryotes). We have to use an electron microscope to see them as they are that small. This was not available until recently.
Which of the following is a lens found on electron microscopes but not on light microscopes?
An electromagnetic lens is found on electron microscopes but not on light microscopes. Electromagnetic lenses use magnetic fields to focus electron beams in electron microscopes, allowing for higher magnification and resolution compared to light microscopes.
