Grades:
There will be 2 two-hour mid-term exams, plus one three-hour final exam. The final grade will be computed as follows:
25% Midterm one
25% Midterm two
15% Recitation
35% Final
There will no make-up for any examination. In extreme medical emergency, a letter from the actual, treating physician is required, as well as at least one hour's notice BEFORE the exam. If the excuse is acceptable, the student's grade will be computed from the other exams and quizzes. Cell phones and pagers are not permitted during quizzes or examinations.
5:20 - 6:00 PM Mondays
Recitation is MANDATORY (In other words, you HAVE to go)
Each recitation (except the first) will end with a 10 minute quiz. There will be no make-up for missed quizzes. The two lowest scores will be dropped in computing the Recitation portion of the grade.
First recitation on September 10 will do problems on photoelectric effect and Planck's Law.
Second recitation on September 17 will do problems on de Broglie relation and Euler's formula.
Third recitation on September 24 will cover the Heisenberg Uncertainty Principle.
Fourth recitation on October 8 will cover Dirac's Bra-ket notation
Fifth recitation on October 15 will cover Reduced Mass.
Sixth recitation on October 22 will cover Electron Spin.
Seventh recitation on October 29 will cover symmetry and anti-symmetry of wavefunctions.
