Suppose the Death Star's laser in Star Wars uses green light at a wavelength of 541.4 nm. A. Calculate the energy in J/mol of this light (i.e. the energy of a mole of photons). B. If the green light is emitted by an electronic transition to n = 4 in the He* ion, what is the initial energy level? Remember that for non-hydrogen atoms, the Rydberg constant is multiplied by a factor of Z2, where Z is the atomic number of the element (i.e. RH*Z?).
