the wave function vanishes outside the box, it must vanish on the walls of the box atx =0andx = a. Since we know that the wave function is comprised of sinusoidal functions we are searching for a wave function with a nodes at x =0 and x = a. Only a pure sine function has a node at the origin. The distance between nodes of a sinusoidal function ...
