Unformatted text preview: E < V , how does the decay parameter depend on E ? If E increases does the wavefunction decay more or less rapidly with distance? 3. Schr odingers equation Solve Schr odingers equation for the one dimensional step potential V ( x ) = ( if x V if x > and calculate the reection coecient. Graph the reection coecient for 0 < E < 2 V . 4. Electron in a 2-D box a) An electron is inside a two-dimensional box with each side of length a . V = 0 inside the box and V = outside. Solve Schrodingers equation and determine the wavefunctions and the formula for the energy levels. b) Calculate the energy of an electron in the 2-D box with sides of length 5 nm for the ground state and the state given by the quantum numbers (3 , 3). List all states with energy equal to or less than the energy of the (3 , 3) state....
