What is the reason that a modern electron microscope (tem) can resolve biological images to the subnanometer level, as opposed to tens of nanometers achievable for the best super-resolution light microscope?
a. the focal length of the electron microscope is significantly longerb. contrast is enhanced by staining with atoms of heavy metalc. electron beams have much shorter wavelengths than visible lightd. the electron microscope has a much greater ratio of image size to real size
