In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
" Living things cannot be viewed with an electron microscope because the process to prepare them for viewing would kill them! " in the paragraph it says this , and i just took the unit 1 test . Its 100% electron microscope .
