BRAINCAKEElectron Microscope
The resolution of a microscope is about half its wavelength.
Electron beams have shorter wavelengths than light. An electron beam of wavelength 1nm would have a resolution of about 0.5nm so the ultrastructure of a cell could be seen.
Disadvantages of the electron microscope are
