Please help me out with this questions. Thank you.
Neutrons can be produced at low temperatures to serve as probes of molecular structure. When the de Broglie wavelength of a neutron is on the order of the dimensions of chemical bond lengths, the diffraction patterns are especially important for molecular structure. If the speed of a thermal neutron is given by the expression v = (3k_BT/m)^1/2, at what temperature will neutrons have a de Broglie wavelength of 50 pm =...
