Which one of these statements is true?
(a) The atomic spacing in crystals is too fine to produce observable diffraction effects with matter waves.
(b) Only charged particles have matter waves associated with them.
(c) Identical diffraction patterns are obtained when either electrons or neutrons of the same kinetic energy are incident on a single crystal.
(d) Electrons, neutrons, and x-rays of appropriate energies can all produce similar diffraction patterns when incident on single crystals.
(e) Wave phenomena are not observed for macroscopic objects such as baseballs because the de Broglie wavelength associated with such macroscopic objects is too long.
