2. (20 points) If a state of an electron can be expanded in the 1D particle in the box (P.I.B.) eigenstates as the following, (x) = 0.64. +0.84, and the box size is 6 , calculate the average energy to be observed in Joule and eV unit. Note: electron mass is 9*10-31 kg, Planck constant is 6*10-34 J's, 72-100. Prove that the total wavefunction is normalized. Is y(x) the eigenfunction of the ID P.I.B. Hamiltonian operator
