WebWhen imposing a periodic boundary condition, the amplitude of the wavefunction at coordinate x must match that at coordinate x + L, so we have: Ψ ( x) = Ψ ( x + L) In your previous 'particle in a box' scenario, you mention that the general form of the wavefunction is given by a linear combination of sine and cosine with complex coeficients. WebSo when you multiply the value of the function by some coefficient and consider the amplitude, which as Sal explains is 1/2 (ymax - ymin)*, you are essentially multiplying 1 (for the max) and -1 (for the min) by that coefficient.
