∙ 13y agoAn electron microscope emits a beam of electrons that pass through certain materials and is recorded at the end. A light microscope illuminates an object placed and the light curves in a certain way that it allows you to see an image magnified. They both in a way use particles light using Photons and electron using electrons.

What details do you see when viewing specimens with the scanning electron microscope?
I can observe cell surface area such as cell wall or outer structure of cell.
What can be considered to be the combination of a proton and an electron?
The pair form a hydrogen atom.There is a fallacy that's taught about this pairing, which is that the electron-proton pair form a neutron. See my answer to the question "What particle has the same mass as a hydrogen atom?" for more details about this, and why it is wrong.
How is the use of a small scale maps different from the use of large scale map?
If details are needed (larger) smaller or fewer details (small)
How is the use of small-scale maps different from the use of large scale maps?
If details are needed (larger) smaller or fewer details (small)
Heart of the matter?
The specific heart of the matter; the practical details.
Why are electron microscopes capable of revealing details much smaller than those through light microscope?
Electron microscopes are capable of revealing details as much as 1000 times smaller than those visible in light microscopes because the wavelengths of electrons are much shorter than those of light.
What are electron microscopes capable of revealing details much smaller than those seen through light microscope?
Because the electron beam has a wavelength lower than visible light.
Why are electron microscopes capable of revealing details much smaller than those shown in a light microscope?
To put it in very simple terms, because the wavelength of an electron is much smaller than the wavelength of visible light.
Why are electrons microscopes capable of revealing details much smaller than those seen through light microscopes?
They're dope like that cx
Why are electron microscopes capable of reveling details much samller than those seen through light microscopes?
electron microscopes are more powerful than light ones.So that is why I answerd.
Why are electron microscopes capable of revealing details much smaller that those seem through light microscope?
The resolving power of a microscope is a linear function of the wavelength - An optical microscope's wavelength is that of light, and the electron microscope's - that of vibrating electrons. As the electron microscope's wavelength is about 100,000 times smaller than that of light, we get a much better resolving power.
True OR FALSE an electron microscope use light to view the details of a specimen?
False, electron microscopes use electrons to view specimens which have been treated with special metallic "dyes". (the clue is in the name)
Are Scanning microscopes used to observe individual atoms?
No. Scanning Electron Microscopes (SEM) use electrons to view microsopic details down to the granular structure of material. Since it uses electrons, it could not detail anything the size of an Atom.
What have modern microscopes made it possible to do?
The microscopes in our days make it easy to see the things that the naked eye can not. Light microscopes see objects down to about 500 nm. A nanometre = 1 metre/ 1000 000 000 Modern microscopes allow scientists to view individual cells but not see well the organelles in them. Electron microscopes are used to get details of organelles. An atom cannot be viewed through a microscope as it is about 1000 times less than the wavelength of visible light. An electron microscope can give the reflection of objects down to about a nanometre or slightly smaller. This is almost possible to view larger atoms.
How it is possible to use the beam of electron in microscope?
That depends on the microscope. A tunnelling microscope uses a "beam" of electrons as a detector - a charged ultra-sharp stylus tracks across a sample using the beam to sense distance to the sample and hence the micro-structure of the surface. In scanning microscopes, the image relies on the fact that electrons can be considered to be waves of very short wavelength. With decreasing wavelength, resolution is possible at increasing magnification - finer details are resolvable.
What is an electron microscope also named?
According to the Encyclopdia Britannica, there are many kinds of electron microscopes:"The transmission electron microscope (TEM) can image specimens up to 1 micrometre in thickness. High-voltage electron microscopes are similar to TEMs but work at much higher voltages. The scanning electron microscope (SEM), in which a beam of electrons is scanned over the surface of a solid object, is used to build up an image of the details of the surface structure. The environmental scanning electron microscope (ESEM) can generate a scanned image of a specimen in an atmosphere, unlike the SEM, and is amenable to the study of moist specimens, including some living organisms.Combinations of techniques have given rise to the scanning transmission electron microscope (STEM), which combines the methods of TEM and SEM, and the electron-probe microanalyzer, or microprobe analyzer, which allows a chemical analysis of the composition of materials to be made using the incident electron beam to excite the emission of characteristic X-rays by the chemical elements in the specimen."More information about electron microscopes may be found on the Encyclopedia Britannica's website:http://www.britannica.com/EBchecked/topic/183561/electron-microscope
What instrument used to see small details of a specimen is the?
Microscope. There are several types of microscopes available depending on the specimen in question. Refer to the site below for more information on the types of microscopes.
