Thermal neutrons are neutrons that move at speeds comparable to those of air molecules at room temperature. these neutrons are most effective in initiating a nuclear chain reaction among 235u isotopes. calculate the wavelength (in nm) associated with a beam of neutrons moving at 7.20 102 m/s. (mass of a neutron = 1.675 x10-27 kg.)
