What else can I help you with?
What is a feature of the scanning electron microscope and is not a feature of the light microscope?
It uses electromagnets.
What feature of an electron microscope allows it to achieve resolution at much higher magnifications compared to a compound microscope?
Light microscopes depend on light being reflected by the particles of the substance being studied. However, sometimes the particles are too small to noticeably reflect the light. Electron microscopes function by sending a beam of electrons through a subject; electrons are so tiny that anything can reflect them.
What feature is common to all microscopes and how is this feature related in the word microscope?
All microscopes have lenses. Some types of lenses are eyepiece lenses, objective lenses, and condenser lenses.
What is the limit of resolution of the transmission electron microscope?
Limitations of standard optical microscopy (bright field microscopy) lie in three areas;The technique can only image dark or strongly refracting objects effectively.Diffraction limits resolution to approximately 0.2 micrometre (see: microscope).Out of focus light from points outside the focal plane reduces image clarity.Live cells in particular generally lack sufficient contrast to be studied successfully, internal structures of the cell are colourless and transparent. The most common way to increase contrast is to stain the different structures with selective dyes, but this involves killing and fixing the sample. Staining may also introduce artifacts, apparent structural details that are caused by the processing of the specimen and are thus not a legitimate feature of the specimen.These limitations have all been overcome to some extent by specific microscopy techniques that can non-invasively increase the contrast of the image. In general, these techniques make use of differences in the refractive index of cell structures. It is comparable to looking through a glass window: you (bright field microscopy) don't see the glass but merely the dirt on the glass. There is however a difference as glass is a denser material, and this creates a difference in phase of the light passing through. The human eye is not sensitive to this difference in phase but clever optical solutions have been thought out to change this difference in phase into a difference in amplitude (light intensity
What feature of Ne makes is a noble gas?
Neon's feature that makes it a noble gas is its full outer electron shell, which makes it very stable and unreactive. This stable configuration means that neon does not readily form chemical bonds with other elements.
What is a feature of the scanning electron microscope and is not a feature of the light microscope?
It uses electromagnets.
Which feature is featured in the transmission electron microscope and not featured on the light microscope?
it uses electromagnets
What is a feature transmission electron microscope has but not light microscopes?
The ability to achieve much higher magnifications and resolutions than light microscopes due to a much shorter wavelength of electrons. Transmission electron microscopes can visualize structures at the atomic level, which is not possible with light microscopes.
Features of scanner?
There is one main feature of a scanner, which is scanning documents. Scanning documents allows a paper document to be viewed as a computer document.
What is the limiting feature of the light microscope?
the study of earth
What is Scanning and indexing?
Scanning: "to look at all parts of (something) carefully in order to detect some feature(s)" Indexing: "the action or process of compiling an index"

What is an electron feature characterized by specific energy?
Orbital
What is the function fuse on dissecting microscope?
The fuse on a dissecting microscope is a safety feature that protects the microscope from electrical damage due to power surges or overloads. If the fuse blows, it will need to be replaced before the microscope can be used again.
Advantages and disadvantages of SEM and TEM?
In SEM (Scanning Electron Microscopy) you look at either backscattered or secondary electrones whereas in TEM (Transmission Electron Microscopy) you look how much of your electron beam makes it through the sample onto your phosphor screen or film camera. Usually SEM is used for surface analysis and TEM for analyzing sections.
How effective is the RFID blocking feature in the passport case you are considering purchasing?
The RFID blocking feature in the passport case is highly effective in protecting your personal information from unauthorized scanning or theft.
What term is used to describe the feature of microscope that makes it possible to move among objective lenses with just minor focusing?
Parfocal is the term used to describe the feature of a microscope that allows for switching between objective lenses with minimal or no need for refocusing. This is a convenient feature that helps maintain focus when switching between different magnifications.
