Determine the energy of the particle if the proposed wave function satisfies the Schrödinger equation for x < 0.
A fellow student proposes that a possible wave function for a free particle with mass \(m\) (one for which the potential-energy function \(U(x)\) is zero ) is$$ \psi(x)=\left\{\begin{array}{ll} e^{-k x}, & x \geq 0 \\ e^{+\kappa x}, & x<0 \end{array}\right. $$where \(\kappa\) is a positive constant.

When we discussed the particle in a box model, we defined our box to be from x=0 to x=a. Re- examine this problem, defining the box to be from -a to +a. Recall that the general solution for a particle in a region of V=0 is ψ = A sin kx + B cos kx. Apply the appropriate boundary conditions, figure out what k is (in terms of a), and normalize your solution (i.e. evaluate A and B). .
