Question

What is the maximum magnification that can usually be achieved by an electron microscope?

Answer 1

Electron Microscope (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. The electron Microscope uses a beam of electrons and their wave-like characteristics to magnify an object’s image, unlike the optical microscope that uses visible light to magnify images.

Complete step by step answer:
Electron microscopes use subatomic particles called electrons to magnify objects. The electrons are fired at the sample very fast. When electrons travel at speed they behave a bit like light, so we can use them to make an image.But because electrons have a smaller wavelength than visible light they can reveal very tiny details.

This makes electron microscopes more powerful than light microscopes.Electron Microscope magnifies an object up to $200,000$ times.Electrons have a much lower wavelength than light ($100000$ times shorter in fact, at $0.004{\text{ }}nm$) which means that they can be used to produce an image with resolution as great as.

Note: The resolution limit of electron microscopes is about $0.2{\text{ }}nm$, the maximum useful magnification an electron microscope can provide is about $1,000,000x$. A light microscope can magnify things up to $2000\,x$ but an electron microscope can magnify between $1$ and $50$ million times depending on which type you use.
