Physics 228 - Analytical Physics IIB

Optics and Modern Physics
Spring 2018

 

Note: Expect small changes throughout the semester.

Syllabus


Textbook

The assigned reading is from our textbook:
Young and Freedman: University Physics, Volumes 2 and 3, 14th Edition, Pearson/Addison Wesley, San Francisco, 2012.

If you purchased the combined volume 2 and 3 for 227, this will suffice for 228. Most of the course will follow volume 3 (Modern Physics).

Please complete the assigned reading before each lecture, and be sure to bring your i-clicker

 transmitter with you to lecture. You may be quizzed on the reading at the beginning of each lecture, and you will be asked to participate interactively throughout the lecture with the i-clicker.

There are web-based homework assignments throughout the semester using This Link.

  • The first deadline for homework assignments is 11:59 PM on Wednesday, January 24.  This is required only for students who did not take Physics 227 in the fall. It is a tutorial assignment (not for credit) that introduces you to Mastering Physics. It is essential to do this before starting to complete problems in Mastering Physics for points, so as not to lose credit for making mistakes in inputting your answers into the system.
  • After that, there will be one set of problems each week, due at 11:59 PM every Sunday, though we encourage you to do them before the weekend.

The problems will be graded by Mastering Physics, which rigidly (automatically) enforces the deadlines for completion.
