The allowed energy levels of the hydrogen atom are described by the following expression:
En=−2.17868×10^−18J(1/ n^2)
where n is the quantum number of the energy level. The Balmer series that is observed in the line spectrum of hydrogen corresponds to transitions that end in the n = 2 level. Determine the wavelengths of the first 5 lines in the Balmer series.
