1) The diagram below shows a part of the energy level diagram from hydrogen according to the Bohr model. Which series in the diagram represents the transitions that give rise to the spectral lines described by the Balmer series?

PHYS 114 Assignment 7 Due back on Friday December 2nd 2011 in class

n=5 n=4 Series C n=3 Series B n=2 Series A

n=1 a) Series A b) Series B c) Series C d) All of the above e) None of the above (1 mark)

2) Determine, in angstroms, the shortest and longest wavelengths of the Lyman series for the hydrogen atom. 3) If you remember from your notes the Balmer series is a given by a special case of the Rydberg formula: 1/λ = K(1/n – 1/m ), where λ is the wavelength of the photon emitted, n and m are integers and K is a constant equal to 1.097 x 107 m-1. What is the longest wavelength photon that can be emitted in the Balmer series(NB If your answer is close to one of the numerical answers choose that answer)? a) 656.3 nm b) 121.5 nm c) 364.6 nm d) 0.00 nm e) None of the above

4) The wavefunction as derived in the Schrodinger equation is best described as being a measuring of which of the following: a) Photon frequency b) Photon wavelength c) Particle wavelength d) Particle phase e) Probability
