Question

The following is an acceptable wavefunctions for a particle in a 2D rectangular box with infinite walls: (12 points) 12/ innxx -intnxx\ / innyy -innyy le Lx - e Lx 1 Ly – e Ly Lx 12Ly 16x9 = (+)* (24)*(7*-77)( ) a. Show that this wavefunction is normalized. (hint: you should expand the exponentials into their trigonemtric forms using Euler's formula) b. Show that the expectation value of px is equal to zero. (hint: use the trigonemtric forms again)
