The wavelengths of the photons emitted by potassium corresponding to transitions from the 4P 3/2 and 4P

Question:

The wavelengths of the photons emitted by potassium corresponding to transitions from the 4P_3/2 and 4P_1/2 states to the ground state are 766.41 nm and 769.90 nm.

(a) Calculate the energies of these photons in electron volts.

(b) The difference in the energies of these photons equals the difference in energy ΔE between the 4P3/2 and 4P1/2 states in potassium. Calculate ΔE.
