Consider an electron in an infinitely deep one-dimensional potential well of width Lz =1 nm . This electron is prepared in a state that is an equal linear superposition of the first three states. Presuming that oscillations in wavefunction amplitude lead to oscillations at the same frequency in the charge density, and that the charge density at any point in the structure give rise to radiated electromagnetic radiation at the same frequency, list all of frequencies (in Hertz) of radiation that will be emitted by this system.
