Question
An electron microscope is superior to an optical microscope in terms of:

Answer

  1. Having better resolving power
Explanation:
The biggest advantage of an electron microscope over optical microscope is that they have a higher resolution and are therefore capable of a higher magnification ( up to 2 million times ). 
However, optical microscopes show a useful magnification up to 1000−2000 times. This is a limit imposed by the wavelength of light. Electron microscopes, therefore, allow for the visualization of structures that would normally be not visible by optical microscopy.
