Explain the following question in detail:
Question: Suppose you want to observe neutron diffraction in a crystal with 0.24nm spacing between lattice planes.
Part I. Find the momentum of neutrons having wavelength equal to this spacing.
Part II. Find the kinetic energy of neutrons having wavelength equal to this spacing.
Part III. If these neutrons constituted an ideal gas, what would be the gas temperature?
Explain the each and every step in derail for help.
