Problems are listed in approximate order of difficulty. A single dot (•) indicates straightforward problems involving just one main concept and sometimes requiring no more than substitution of numbers in the appropriate formula. Two dots (••) identify problems that are slightly more challenging and usually involve more than one concept. Three dots (•••) indicate problems that are distinctly more challenging, either because they are intrinsically difficult or involve lengthy calculations. Needless to say, these distinctions are hard to draw and are only approximate.
• Two equivalent definitions of the Rydberg energy ER are
(a) Using the definition (5.18) of aB, verify that these two definitions are equivalent, (b) Find the value of ER from each of these expressions. (In the first case use ke2 = 1.44 eV · nm and the known value of aB; in the second, multiply top and bottom by c2, and then use the known values of mc2, ke2, and ℏc.)
