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.

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.
A light microscope uses a man made light, but a Electron microscope has electron beams focuse on the specimen.
electron microscopes use beams of electrons to create a 3D image, while Light Microscopes are limited to the wavelength of light (around 500nm)
transmission electron
an electron microscope can magnify something up to 500,000 times
An Electron Microscope uses electrons to magnify objects.
Transmission Electron Microscope and Compound Light Microscope
sliced microscope and the treated microscope
when you need to magnify much smaller objects then optical microscopes
Yes, there are all kinds of microscopes. Everyone can magnify objects some just magnify more than others.
Microscopes cannot view viruses as viruses are smaller than the wavelength of visible light (about 0.2 microns). To view extremely tiny objects, scientists use electron microscopes. Electron microscopes use electron beams instead of light to magnify objects less than 1nm!
they magnify every thing because their mikeroscopes
what magnification is electron microscope capable of
light microscopes direct light onto the slide and magnify it, light microscopes also have a high and low power objective lens which can magnify up to 10, 40, 43 and 100 times total magnification whilst electron microscopes shoot electrons at the slide which give more detail and accuracy but the disadvantage is it can't view objects in color. electron microscopes can magnify up to 500.000 times total magnification.Light microscopes aren't as strong as an electron microscope in respect to zooming power. The specimen can remain alive in light microscope but for electron microscopes, preparation of the slides will kill the specimen.

No, they use lenses. :)
An Electron Microscope uses electrons to magnify objects.
A electron microscope uses a beam of electrons instead of light to magnify objects up to 500,000 times actual size. A electron microscope has much higher resolving power than light microscopes.
Both microscopes and telescopes use lenses to magnify objects. But, telescopes are large and collect light from stars and planets to magnify them, while microscopes are small, can sit on a desktop, get light from the room or a small builtin light and are used to magnify tiny objects.
