This course will give an intermediate level treatment of waves and wave motion, primarily electromagnetic and optical waves. Techniques for producing, modifying and measuring optical waves as well as applications to imaging, sensing, and communications will be discussed.
Catalog course description: Wave phenomena with specific applications to waves in media and electromagnetic phenomena. Wave equations, propagation, radiation, coherence, interference, diffraction, scattering. Light and its interactions with matter, geometrical and physical optics. Experiments for this course are covered in Physics 308.
Prerequisites Physics 205, 241, or 244, and Physics 311. Physics 322 or concurrent enrollment recommended.
The course textbook is J. Peatross and M. Ware Physics of light and optics. Available as a free download from optics.byu.edu/textbook.aspx
It can be purchased in a printed bound form from http://www.lulu.com/product/paperback/physicsoflightandoptics/14241717.
The textbook will be supplemented by material from Optics for Physicists (OfP) which will be provided as a download from this webpage.

Homework
Homework will count for approximately 50% of your grade. You are encouraged to work with others on solving the HW problems but you must turn in your own work  not a copy of work done by others. It is encouraged to use software such as Mathematica or Matlab for the homework. It is perfectly acceptable to turn in your homework solutions in the form of a Mathematica notebook. Homework is due printed on paper at the beginning of class on the assigned date. Late homework will only be accepted if you have received prior permission to turn it in late.
Most homework problems are worth 3 points which will be awarded as follows:
3  Correct solution or minor errors.
2  Substantial effort but missing some important parts of the solution.
1  Limited effort, far from correct.
0  No effort, or insignificant attempt.
Assignments and solutions will be provided via email.
