Write out the hydrogen wave functions cnℓmℓ for φ nℓmℓ values of (2, 1,-1), (2, 1, 0), and (3, 2, -1).
While studying the spectrumn of a gas doud in space, an astronomer magnifies a spectral line
that results from a transition from a p state to an s state, She finds that the line at 575.050
nm has actually split into three lines, with adjacent lines 4.70 x 10- nm apart, indicating
that the gas is in an external magnetic field. (Ignore effects due to electron spin.)
What is the strength of the external magnetic field?
O B=3.25 T
OB-2.98 T
O B=2.79 T
O B=3.05 T
OB=2.05 T
What do we need to do to average over Θ and ф to get the probability that the electron is inside a shell of radius r and thickness dr?
