Chapter 5, Problem 5.58SP

According to the equation for the Balmer line spectrum of hydrogen, a value of $n=3$ gives a red spectral line at656.3 nm, a value of $n=4$ gives a green line ar 486.1 nm,and a value of $n=5$ gives a blue line at 434.0 nm. Calculate the energy in kilojoules per mole of the radiation corresponding to each of these spectral lines.
