Schrodinger’s Wave Equation (5 points each): A one-dimensional infinite potential well with a width of 1.2 nm contains an electron. (a) Calculate the first two energy levels that the electron may occupy. (b) If an electron drops from the second energy level to the first, what is the wavelength of a photon that might be emitted? (c) For the lowest energy state, find the average momentum p x and the average energy E.
