a) The Balmer series consists of transitions in hydrogen from higher states where n > 2 to the n = 2 state. Use the Bohr model to show each ‘line’ in the Balmer series can be described by the following equation; 1/λ = R(1/22 -1/n2) where the Rydberg Constant R = me4/8εo2 h3c b) Use this result to confirm the wavelength of light emitted in the Hα transition. c) Develop similar equations for the Lyman, Paschen, Brackett and Pfund spectral series where where the final states are n= 1, 3, 4 and 5 respectively.

Transcribed Image Text:1. a) The Balmer series consists of transitions in hydrogen from higher states where n > 2 to
the n = 2 state. Use the Bohr model to show each 'line' in the Balmer series can be
described by the following equation;
1/λ = R(1/2² -1/n²) where the Rydberg Constant R = me4/8ε.² h³c
