1) Lines in the Brackett series of the hydrogen spectrum are cause by
emission of energry accompanying the fall of an electron from outer
shells to the fourth shell. The lines can be calculated using the
Balmer-Rydberg equation.

e m = 4, R = 1.097 x 10-2nm-1 , and n is an integer greater than 4.
Calculate the wavelengths (in nanometers) and energies (in kilojoules
per mole) of the first two lines in the Brackett series. In what region
of the electromagnet spectrum do they fall.
