following your tip i tried to solve it like so: Let the general solution to a finite well from 0 to L be ##\psi=Bsin(kx)+Acos(kx)## then i apply the periodic condition such $$\begin{cases}\psi(0)=\psi(L)\\ \psi '(0)=\psi '(L)\end{cases},$$ Solving the system gives...

thank you again!

Thank you! i would have never thought. so in this case do i just take my solutions for the potential well,with $$ \psi=\sqrt{2/L}sin(\frac{n\pi x}{L}) \\L\to\infty $$ doesn't it make ##\psi=0## ?

thank you for that, i may be missing notes, is there any good book where i can find more?

no i have not, i just recently started studying potentials and as of my class notes i have written that acceptable wave eigenfunctions must be normalizable, is it not so?

Hi, this was one of the oral exam questions my teacher asked so i tried to solve it. Consider y>0 the energy spectrum here is continuous and non degenerate while for y<0 the spectrum is discrete and non degenerate because E<0. for y>0 i thought of 2 cases case 1 there is no wave function for...
