Why is the resolution of an electron microscope on the order of the electron wavelength?

The wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus the resolution of an electron microscope is theoretically unlimited for imaging cellular structure or proteins. Practically, the resolutionis limited to ~0.1 nm due to the objective lens system in electron microscopes.
