Here are the energy levels in a fantasy hypothetical hydrogen-like atom. (You cannot use the Rydberg constant, 2.18 x 10-18 J, for this problem, therefore). What is the frequency of a photon that is absorbed when an electron goes from level 2 to level 4? Energyn = 4 -2.10 x 10-19 Jn = 3 -3.20 x 10-19 Jn = 2 - 5.20 x 10-19 Jn = 1 - 9.80 x 10-19 J
