Homework:

Assignment 1, due Jan 27:   Griffiths problems 5.2, 5.6, 5.11, 5.16, 5.33, and 5.36 [part (a) only]

            solutions   average: 14.8/18

Assignment 2, due Feb 3:   Griffiths problems 5.19, 5.20, 5.22, 5.24, and 5.27

            solutions   average: 13.7/15

Assignment 3, due Feb 10:   Griffiths problems 5.29, 6.2, 6.3, and 6.29

solutions   average: 8.7/12

Assignment 4, due Feb 17:   Griffiths problems 6.5, 6.9, 6.11(a), 4.43(c), 6.13, 6.32

            solutions   average: 15.8/18

Assignment 5, due Feb 24:   Griffiths problems 6.14, 6.16, 6.18, 6.33

            solutions   average: 10.4/12

 

Assignment 6, due March 17:  Griffiths problems 6.23, 6.26, 6.27, 6.36, 6.38   Average: 11.4/15

           

Assignment 7, due March 24:  Griffiths problems 7.3, 7.6, 7.9, 7.10, 7.12  Average 11.0/15

 

Assignment 8, due March 31:  Griffiths problems 11.4, 11.7, 11.19   Average 7.2/9

 

Assignment 9, due April 7:  Griffiths problems 11.9, 11.12, 11.13, 11.16    Average 10.8/12

 

Assignment 10, due April 21:  Griffiths problems 9.2, 9.4, 9.6, 9.18, 9.20    Average 8.5/15

  

Assignment 11, due April 28:  Griffiths problems 9.8, 9.11, 10.2, 10.9     Average 9.4/12

   In problem 9.11, only calculate the lifetime of the 2p, m = +1 state (but do it explicitly, don’t just use my result for the m = 0 state and a symmetry argument).

   For problem 10.2, you’ll need to read through example 10.1 on pages 374-375.
