Why are electron microscopes capable of revealing details much smaller than those seen through light microscopes?
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 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.
Is an electron microscope used to magnify a living specimen?
An EM is basically of 2 types. Scanning Electron Microscope and Transmission Electron Microscope. Yes definitely it is used to magnify and resolve specimens but a living specimen cannot be used. Only dead are used. This is due to certain disadvantages that come along with this microscope. If need further details over the microscope uses and types then let me know.yea...i completely agree wif yuh... :)
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
Produces greatly magnified images of surface details?
A scanning electron microscope produces greatly magnified images of surface detail. It functions by scanning a sample with a focused ray of electrons.
Simple staining is often necessary to improve contrast in what microscope?
The type of microscopy that uses chemical stains to add color and increase contrast is light. The type of microscope that can be used to observe very small surface details is called a scanning electron.
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)
What kind of microscope would you use to view living specimens?
A regular microscope, use the 500X for details.
What microscope is used to see details of a 300 nm virus?
electron microscope
What microscope enables the viewing of fine internal structural details of cells?
Electron microscope
An electron microscope uses light to view the details of a speciman?
true
What microscope type is used to see the detail inside a cell?
You have turn the fine adjustment knob to see the cell.
What is the resolution power of a transmission electron microscope?
The Transmission Electron Microscope (TEM) was the first type of Electron Microscope to be developed and is patterned exactly on the Light Transmission Microscope except that a focused beam of electrons is used instead of light to "see through" the specimen. It was developed by Max Knoll and Ernst Ruska in Germany in 1931.The first Scanning Electron Microscope (SEM) debuted in 1942 with the first commercial instruments around 1965. Its late development was due to the electronics involved in "scanning" the beam of electrons across the sample. TEM focus a beam of electrons through a specimen while SEM focus a beam of electrons onto the surface of a specimen and the image provided is 3-Dthe transmission microscope magnifies 300,000 more times and the scanning microscope only magnifies 100,000 more the transmission gives the image of the inside and the scanning microscope gives a 3D image of the surface of the specimen
Why scanning electron microscope must operate in vacuum?
A scanning electron microscope (or SEM) doesn't use photons (light) to create an image, it uses electrons. Electrons have a much smaller wavelength than photons do, so this allows them to "see" smaller details in an object than a photon can. Unfortunately, electrons are also a lot bigger, so when travelling through air, they are more likely to crash into air molecules and get sent off course. Obviously, if the electrons can't travel in a straight line, they can't be used to make a nice image. That's why an SEM needs a very good vacuum to create a good image.
