The resolving power of a microscope is proportional to the wavelength used. A resolution of approximately 5.4 × 10-11 m (0.054 nm) would be required in order to "see" an atom.
a) If electrons were used (electron micro-
scope), what minimum kinetic energy would be required for the electrons. Planck's constant is 6.63 × 10-34 J · s.
b) If photons were used, what minimum photon energy would be needed to obtain5.4 × 10-11 m resolution? The speed of lightis 3 × 108 m/s .
Answer in units of keV.
