Part A:

First find the energy using the equation: E= hc/lamba. Use the wavelength given. It should be around 7.5 eV.

Using the calculated energy, use E=13.6eV (Z^2/n^2) to find the initial state (n). Z for He is 2.

Part B:

Using the energy calculated in part A and the initial state, input the values to:

E=13.6((1/n final^2) – (1/n initial^2)) to find n final
