Question
The wave nature of electrons makes an elec- tron microscope, which uses electrons rather than light, possible. The resolving power of any microscope is approximately equal to the wavelength used. A resolution of approxi- mately 1.0×10−11m would be required in order to â€see†an atom.A) If electrons were used, what minimum ki- netic energy of the electrons (in eV) would be required to obtain this degree of resolution? The speed of light is 3×10*8m/s and Planck’s constant is 6.63×10−34J ·s. Answer in units of eV
B)
If photons were used, what minimum photon energy would be required? (in eV)

Explanation / Answer
a>10^(-11)=h/(mv)
KE=14462.36ev
b>h*c/(lamda)
119101.7964 ev
