An infinite deep one dimensional Square will has x=0 and X=L. Two small perturbing Potentials of width 'a' and height 'V' are located at x = 4/4 and x = 34/4, where acc toos shown in figure. What will be the difference in the energy shifts between n = 2 and n=4 chergy due to this perturbation ? L levels
