. An electron in a long organic molecule used in a dye laser behave approximately like a particle in a box with width 4.18 nm. (a) What is the λ of the proton emitted when the electron undergoes a transition from the first excited level to the ground level.                                                                                                                         (b) What is the λ of the proton emitted when electron undergoes a transition from the second excited level to the first excited level?
An electron trapped in a one-dimensional infinitely deep potential well with a width of 250 pm is excited from the first excited state to the third excited state. What energy must the electron acquire for this quantum jump to occur? The electron then emits a photon and transitions to the ground state. Determine the wavelength and momentum of the emitted photon.
An electron is bound in a square well of width 1.05 nm and depth U0=6E∞, where E∞ is the ground-state energy for an infinitely deep potential well.If the electron is initially in the ground level,  E1=0.625E∞ , and absorbs a photon, what maximum wavelength can the photon have and still liberate the electron from the well?
