An electron microscope uses a potential difference of 100 keV togenerate a beam of electrons. The limiting resolution of amicroscope is expressed as:
d = / 2NA
Where NA is the numerical aperture and is approximately 0.95
a. What is the kinetic energy of the electrons?
b. What is the wavelength of the electrons?
c. What is the limiting resolution of the electrons?
d. How does this resolution compare to an optical microscope?
