Q. The resolving power of a microscope depends on the wavelength used. If you wanted to "see" an atom, a wavelength of approximately 1 × 10-11 m would be required. (a) If electrons are used (in an electron microscope), what least amount kinetic energy is required for the electrons? (b) What If? If photons are used, what minimum photon energy is needed to get the required resolution?
