A microscope can resolve as two distinct objects of featuresthat are no closer than the wavelength of the light or electronsused for the observation.

a) with electron microscopes, what energy is needed for aresolution of 0.4Ã

b) what photon energy would be required of an optical microscopefor the same resolution?

The resolving power of a microscope depends on the wavelength used. If you wanted to "see" an atom, a wavelength of approximately would be required. (a) If electrons are used (in an electron microscope), what minimum kinetic energy is required for the electrons? (b) What if photons are used, what minimum photon energy is needed to obtain the required resolution?

What Equation should I use?

The resolving power of a microscope is proportional to thewavelength used. A resolution of 1.0 10-11 m (0.010 nm) would berequired in order to "see" an atom.
