3. Excited hydrogen. The energy levels of atomic hydrogen are given by the expres- sion E= -13.6/m electron volts, where n denotes the principal quantum number. Consider the atomic hydrogen in a stellar atmosphere, and specify that the ambient temperature is 7,000 K. For atomic hydrogen, what numerical values do the following probability ratios have? (a) (b) probability that electron has n=2 and no orbital angular momentum probability that electron has n = 1 probability that electron has n = 2 (without specification of orbital angular momentum) probability that electron has n = 1 3.
