Question

Quizplus · Accepted Answer

The de Broglie wavelength is given by the equation λ = h/p, where h is Planck's constant and p is the momentum of the particle. The momentum of the neutron is p = mv, where m is the mass of the neutron and v is its speed. Substituting these values into the equation for the de Broglie wavelength, we get:λ = h/p = h/(mv) = (6.626 × 10^-34 J s)/(1.67 × 10^-27 kg × 5.0 m/s) = 79 nmTherefore, the de Broglie wavelength of the neutron is 79 nm.
