Electrons accelerated through a potential of 100 kV pass through a crystal with a mean inner potential V of 30 volts. Calculate the mean refractive index, n, of the crystal, where: n = λ0/λv, and λ0 is the wavelength of electrons in vacuum and λv is the wavelength of the electrons in the specimen. (Hint: The electron energy, kinetic plus potential, is conserved.)
