The resolving power of a microscope depends on the wavelength utilized. If one wished to "see" a particular type of molecule, a resolution of 1.2*10-10 m would be required.
a) If electrons are utilized (in an electron microscope), what minimum kinetic energy is required for the electrons?
(b) If photons are used, what minimum photon energy is required to obtain the required resolution?
