Physics 314 Homework & Spring 1999
- Assignment 1 - due Friday Feb. 5th
- Griffiths, problem 5.5
Hint: <x>n = a/2 and
<x²>n = a²(1/3 - 1/(2[n
]²) for the infinite square well; see Section 2.2.
- Griffiths, problem 5.11
Hint: The case of Nitrogen in part e) is tough - you need to
carefully consider how to satisfy the antisymmetrization requirement. You
might want to recall Clebsch-Gordon coefficients...
- Griffiths, problem 5.12
- Griffiths, problem 5.13
- Griffiths, problem 5.16
Note: Maple might be useful here...
- Assignment 2 - due Friday Feb. 12th
- Griffiths, problem 5.19
- Griffiths, problem 5.27
Hint: again, something like Maple might be useful here...
- Griffiths, problem 5.29
- Griffiths, problem 5.30
Aside: physical systems are known that are, to a good
approximation, two-dimensional, so the problem is not as artificial as it may
seem...
- Griffiths, problem 5.31
- Assignment 3 - due Friday Feb. 19th
- Griffiths, problem 6.1
- Griffiths, problem 6.3
- Griffiths, problem 6.32
Hint: You will not have to actually calculate 9x9=81
integrals - many of them you can show by simple arguments must be zero!
Other Hints:
is even in powers of cos(theta)
- Assignment 4 - due Friday March 5th
(but will be accepted Mon. March 15 in class, after spring break)
- Griffiths, problem 6.21
- Griffiths, problem 6.26
- Griffiths, problem 6.33
- Assignment 5 - due Friday March 19
- Griffiths, problem 7.2
- Griffiths, problem 7.5
- Griffiths, problem 7.11
- Assignment 6 - due Friday March 26
- Griffiths, problem 7.3
Note: "triangle trail function" in the question
should read "triangle trial function" (I have this vision of a
trail of little triangles wandering off into the sunset...)
- Griffiths, problem 7.7
Note: you should not need to evaluate
any new integrals...
- Griffiths, problem 7.10
Note: Maple or something similar
might be useful here...I also think this should be labelled a ** problem.
- Assignment 7 - due Friday April 2
- Griffiths, problem 7.13
Note: I think this
one should be a ** or *** problem.
- Griffiths, problem 8.2
- Griffiths, problem 8.3
- Assignment 8 - due Monday April 19
- Griffiths, problem 9.6
- Griffiths, problem 9.7
- Griffiths, problem 9.8
- Griffiths, problem 9.10
- Assignment 9 - due Friday April 30
- Griffiths, problem 11.1
- Griffiths, problem 11.3 Hint: you might Equation [4.34]
to be useful...
- Griffiths, problem 11.7
