Question: The highest achievable resolving power of a microscope is limited only by the wavelength used; that is, the smallest item that can be distinguished has

The highest achievable resolving power of a microscope is limited only by the wavelength used; that is, the smallest item that can be distinguished has dimensions about equal to the wavelength. Suppose one wishes to "see" inside an atom. Assuming the atom to have a diameter of 100pm, this means that one must be able to resolve a width of, say, 10 pm.
(a) If an electron microscope is used, what minimum electron energy is required?
(b) If a light microscope is used, what minimum photon energy is required?
(c) Which microscope seems more practical? Why?
