Problem
Two prominent lines of the Balmer series of hydrogen have measured wavelengths 656.3nm (red) and 486.1nm (blue-green).
(i) Identify the pairs of principal quantum numbers (n1,n2) corresponding to each of these lines.
(ii) Using the two measured wavelengths, calculate a value for the constant that appears in the hydrogen spectrum equation.
(iii) Compare your calculated value with the accepted value 1.097×107m−1 and comment on the percentage difference.
