An electron is contained in a one-dimensional box of length 0.607 nm.
(a) Draw an energy-level diagram for the electron for levels up to n = 4.
(Do this on paper. Your instructor may ask you to turn in this work.)
(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.
