Presentation Transcript

  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 email from Monday for more details (email 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
