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
