Assignment:
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.
1/λ = R (1/m2 - 1/n2 )
where 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.
Provide complete and step by step solution for the question and show calculations and use formulas.
