What is the kinetic energy of each electron in a beam of electrons if the beam produces a diffraction pattern of a crystal which is similar to that of a beam of 1.00 eV neutrons? Note: The electron mass is 9.11 × 10–31kg; and the neutron mass is 1.67 × 10–27 kg.



I know the answer is 1830 eV, but I have no idea how to get this answer.


Can someone please help? Can you provide a thorough explanation, step-by-step, not just the answer.


Thanks so much!
