Homework Statement Suppose that there is a wavefunction \Psi (x,0) where 0 is referring to t. Let us also say that a(k) = (C\alpha/\sqrt \pi )exp(-\alpha^2k^2) is the spectral contents (spectral amplitudes) where k is defined as wavenumber k. \alpha and C is some constant My question is, why...

Thanks. I got it.

Homework Statement Suppose that there is a beam of neutrons with a range of wavelengths. One intends to produce neutrons of single wavelength by the use of neutron mechanical velocity selector. The question is, if the slot in the disk B (second disk) of the selector lags the slot in the disk...
