The discussion focuses on calculating the five longest wavelengths of the Lyman series in hydrogen. The key formula used is ΔE = hc/λ, where ΔE represents the energy difference between initial and final states, and λ is the wavelength. To determine the longest wavelengths, one must minimize ΔE, which occurs when the initial state is n=2 and the final state approaches infinity. The five longest wavelengths correspond to transitions from n=2 to n=3, n=4, n=5, n=6, and n=7.
