How do microscopes differ from electron microscopes?
The microscopes one would think of in a college or high school biology lab are optical microscopes (ie: compound and stereo microscopes) and use light and glass optics in the eyepieces and objective lenses to obtain higher levels of magnification than the human eye can achieve. An electron microscope uses a beam of, you guessed it, electrons to illuminate and produce a magnified image. Electron microscopes are used when the specimens are too small for optical microscopes as they have wavelengths around 100,000 times shorter than visible light and can achieve magnification levels of up to 10,000,000x.
What are the differences between scanning and transmission electron microscopes?
A transmission electron microscopes (TEM) can magnify a sample up to one million times. The sample must be cut extremely thin. An electron beam is directed onto the sample to be magnified and some of the electrons pass through and form a magnified image of the specimen. A scanning electron microscope (SEM) can magnify a sample up to 100,000 times. A sharply focused electron beam moves over the sample to create a magnified image of the surface. Some electrons in the beam scatter off the sample and are collected and counted by an electronic device. Each scanned point on the sample corresponds to a pixel on a television monitor; the more electrons the counting device detects, the brighter the pixel on the monitor is. As the electron beam scans over the entire sample, a complete image is displayed on the monitor. SEMs are particularly useful because they can produce three-dimensional images of the surface of objects. A SEM scans the surface of the sample bit by bit while a TEM which looks at a sample all at once. The scanning transmission electron microscope (STEM)combines elements of an SEM and a TEM and can resolve single atoms in a sample.
What is the difference in the way light microscropes and electron microscopes produce images?
There compared by frist the electron micrscope the electron microscope you can cut into a cell (any) and there huge they can zoom into about 2000X.The light microscope has a light to see [other one doesn't need] and light one can only zoom to 20X.
Why electron is called electron?
Electron microscopes fire a beam of electrons at a target, then measure exactly how they are reflected. (electrons exist as particles & waves) A computer then generates an image from the data recieved. Also, cheese.
Which type of microscope can observe non-living cells?
A tunneling electron microscope cannot image live specimens.
Electron microscopes use a beam of light to produce a magnified image.?
It uses electron beam
Light microscopes use beams of electrons to produce magnified images?
No, a light microscope uses focused light (photons) to produce a magnified image. An electron microscope uses beams of electrons to create a magnified image.
Is light microscopes use beams of electrons to produce magnified images?
No, a light microscope uses focused light (photons) to produce a magnified image. An electron microscope uses beams of electrons to create a magnified image.
Do electron microscopes focus electron beams to create a magnified image of an object?
yes

What does an electron microscope use to produce a magnified image?
a ray of light
What is the smallest thing that the electron microscope can see?
Electron microscopes use a particle beam of electrons to illuminate the specimen and produce a magnified image with better than 50 pm resolution and magnifications of up to about 10,000,000 times.
What is the difference in the way light microscopes and electron electron microscopes produce images?
light microscopes allow light to pass through the specimen and use two lenses to form an image. Electron microscopes use beams of electrons, rather than light, to produce images.

Why there is more detail in an image produced using a TEM than in the image from a light microscope?
An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes.
