Question

An electron is contained in a one-dimensional box of length 0.562 nm. (a) Draw an energy-level diagram for the electron for levels up to n = 4. (b) Photons are emitted by the electron making downward transitions that could eventually carry it from the n = 4 state to the n = 1 state. Find the wavelengths of all such photons: λ4 → 3, λ4 → 2, λ4 → 1, λ3 → 2, λ3 → 1, λ2 → 1 {149, 86.8, 69.4, 208, 130, 247 nm}
