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.

∙ 14y agoElectron microscopes have much greater resolving power than light microscopes that use electromagnetic radiation and can obtain much higher magnifications of up to 2 million times, while the best light microscopes are limited to magnifications of 2000 times. Both electron and light microscopes have resolution limitations, imposed by the wavelength of the radiation they use. The greater resolution and magnification of the electron microscope is because the wavelength of an electron; its de Broglie wavelength is much smaller than that of a photon of visible light.

Electron microscopes use a beam of light to produce a magnified image?
An Electron Microscope uses electrons to magnify objects.
Explain the difference between a light scanning and electron microscope?
A scanning electron microscope will scan the surface and an electron microscope looks inside.
What type of microscope would be best to use to look at different cells or organelles?
scanning electron microscope
To see objects smaller that those that can be resolved by a light microscope. You usually use microscope's that employ a beam of?
You can use an electron microscope to view objects smaller than light photons, which uses electrons as the name suggests
Contrast the way light microscopes and electron microscopes magnify objects?
Sample illumination is achieved in different ways in a light and electron microscope.In a light microscope, the sample is illuminates with light (photon energy)In an electron microscope, the sample is illuminated by a beam of electrons.Devon
Which microscope do not use a beam of light?
Electron Microscope
Electron microscopes use a beam of light to produce a magnified image?
An Electron Microscope uses electrons to magnify objects.
How does an electron microscope differs from a light microscope?
The light microscope use the visible light; the electron microscope use an electrons beam.
What microscope use a beam of electrons instead of light?
An electron microscope.

What does an electron microscope use to produce images?
a beam of electrons
How does the electrons microscope work?
An electron microscope use a beam of electrons instead visible light as source of illumination.
What is a transmission electron microscope used for diagnosis?
The transmission electron microscope operates on the same principle as the light microscope but uses electrons instead of light. What you can see with a light microscope is limited by the wavelength of light. Transmission electron microscopes use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with light microscope.
What type of microscope would be best to use to look at different cells or organelles?
scanning electron microscope
What are the two types of electron microscopes?
Biologists use two main types of electron microscopes. Transmission electron microscopes (TEMs) shine a beam of electrons through a thin specimen. Scanning electron microscopes (SEMs) scan a narrow beam of electrons back and forth across the surface of a specimen.
