The interatomic spacing in a crystal of table salt is 0.282 nm. This crystal is being studied in a neutron diffraction experiment, similar to the one that produced the photograph in Figure 29.12a. How fast must a neutron (mass = 1.67 × 10-27 kg) be moving to have a de Broglie wavelength of 0.282 nm?
