Problem 17 Which of the statements are CORRECT about a particle confined in the 1D infinite potential well V(x) with V(x) = 0 in the well (with well width = W).
(A) The ground state energy aligns with the bottom of the well.
(B) For the first excited state, the uncertainty in the position is of the order of W.
(C) Let 1 = wavelength of the ground state standing wave. Then I is of the order of W.
(D) Let p = momentum of the ground state. The p is of the order of 'h/W, with the uncertainty in p being of the same order as p (h = Planck constant).
(E) None of the above.
