a. An electron is trapped in a one-dimensional box that is 501nm wide. Initially, it is in the n=3 energy level but after a photon is absorbed it is in the n=8 energy level. What is the wavelength of the absorbed photon? b. Eventually the electron ends up in the ground state as photons are emitted. i. wavelength of the least energetic photon? ii. wavelength of the most energetic photon?
