vector that is equal to A+B
O magnitude: 46.4 m; direction: 102°
O magnitude: 20.6 m; direction: -71.1°
O magnitude: 46.4 m; direction: -770
O magnitude: 20.6 m; direction: -78.20

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
