Calculate the wavelength corresponding to an electron with the energy of 94 eV (kiloelectronvolt). Give your answer in Angstrom (10-10 m, for example, if the answer is 1.6x10-10 m, then write 1.6 as your answer). This should give you a good idea why one can use a crystal lattice with an average interatomic distance of around 10-10 m to observe electron diffraction.
A beam of X-rays of first-order wavelength 1.5406 Å is diffracted by a cubic crystal
