[Finite potential well] Consider a symmetric square well potential of a finite depth, i.e., V(x) = 0 inside the well, V(x) = V outside the well. NOTE: for a general discontinuous potential the boundary conditions are the continuity of both the wave function and its first derivative at the point(s) of the discontinuity of the potential y (x_)=y(x),y'(x_)=y'(x4) (i) What are the functional forms of the solutions for y(x) inside and outside the well? (ii) What are the explicit continuity...
