The Wave Function for a Particle in a One-Dimensional Box $\Psi$

The wave function for a particle in a one-dimensional box of length L

A) is constrained by the boundary conditions $\Psi$ (0) = 0 and $\Psi$ (L) = 0.
B) must be zero everywhere outside of the box.
C) is given by $\Psi$ (x) = A sin kx, where A is a constant.
D) restricts the possible energy of the particle to E = .
E) All of these are correct.
