1. Announcements 2/8/12 Prayer Exam review lecture on Friday
Sign up for one of the exam review problems (I’m passing around a sheet).
There are 10 problems. Each problem will get 2-3 students. Do not be the third student to sign up for a problem until all problems have 2 students.
Pass the sign-up sheet back and I’ll read out the final groups at the end of class.
See my from Monday for more details ( me solution in pdf form, etc.)

2. Reading Quiz An “optic axis” is a direction for which:
one of the two n values is complex
one of the two n values is equal to 1
the two n values are the same
the two n values sum to 1

3. Example 4 from last time
in x-z plane, and
n = 1.3 is one of the n’s

4. Reading Quiz In a uniaxial crystal, the index of refraction matrix,
has the form: c. d.

5. Uniaxial Crystals

6. Optic axis along surface
Normal incidence

7. Reading Quiz
In a uniaxial crystal, which vector always obeys Snell’s law?
k (wavevector)
S (Poynting vector)
neither k nor S

8. Thought question (ungraded)
T/F: In the situation depicted (note the orientation of the z-axis!), s-polarized light will see n=no inside the crystal, regardless of angle.
True
False

9. Optic axis perpendicular to surface
At an angle
s-polarized (easy!)…

10. Optic axis perpendicular to surface
p-polarized (hard!)
“Snell’s Law” replacement
Direction of Poynting vector (energy flow)

11. Exam 1: Chapters 1-5 Starts Fri, Feb 10 Ends Tues, Feb 14 Exam info
10 multiple choice problems, 1.5 pts each
A few are from the true/false review questions. I won’t tell you the answers to the T/F questions, but you should definitely talk amongst yourselves.
8 worked problems
Two of them involve written explanations
One involves sketching a few graphs
One is a review problem we’ll cover Friday (lucky group!)
Expected average time: 2 hours
