Question Part B What is the energy (in eV) of a photon, Ephoton, that is emitted when an electron in hydrogen undergoes a transition from the n=4 to the n=2 energy level? Ephoton = Part C – Use the energy in eV you calculated above this question. What is the energy of a photon in Joules (J) emitted when an electron in hydrogen undergoes a transition from the n=4 to the n=2 energy level? Report your answer to three significant figures. Ephoton = Part D – Now that you have the energy of the photon in Joules, use the equation above to: Calculate the wavelength (in nm) of this transition. Report your answer to three significant figures. Part F If an electron moves from the n=2 to the n=4 energy level, energy is absorbed by the atom. Explain this.
