Homework

Homework assignments are due at the beginning of class. Homework assignments are either distributed in lecture or on this web page.

Lab Report

Lab reports are to be handed in to your lab instructor on week following running the experiment. Late lab report will receive partial credit. All lab reports must be turned in to avoid an incomplete grade.

Reading Assignments

The lecture will be in general follow the reading assignments (listed in the following table); therefore you are recommended to read the material ahead of the lecture.
