A beam of neutrons (m = 939.6 MeV/c²) of momentum 12 keV/c is passed through a single slit of width 0.1 nm. As a result of this, the neutron beam acquires an uncertainty in the component of the momentum that is transverse to the beam direction. The distance between the slit and a screen onto which the neutrons are projected is 1.5 m. Using the uncertainty principle, estimate the expected width of the neutron distribution on the screen.

The Answer of A beam of neutrons (m = 939.6 MeV/c²) of momentum 12 keV/c is passed through a single slit of width 0.1 nm. As a result of this, the neutron beam acquires an uncertainty in the component of the momentum that is transverse to the beam direction. The distance between the slit and a screen onto which the neutrons are projected is 1.5 m. Using the uncertainty principle, estimate the expected width of the neutron distribution on the screen.
