Consider an infinite beam of free (V=0) particles with mass m propagating with a consta nt velocity (v=10000 m/s) to the right in one dimension along x. The stationary wave function of the particles is (z) = ceik, where c and k are constants. == Suppose that the density of the bean is such that there are 100 particles passing a given point.xo per second. What should be the normalization constant c to represent such a beam?
