Answer:
1.Due to the fact electron microscope uses beam of electrons rather than rays of light.And beam of electrons has shorter wavelength and therefore higher resolution and magnification compare to light microscope.
2.Due to the fact that they are negatively charged;and therefore it is easier to to adjust their focal length with the use of electromagnets.(electromagnets are certain magnet that can be used to deflects electron s from their paths)
