I’ve uploaded some files you might want to look at.

The first one describes how complex numbers and complex algebra can be used to conveniently represent phasors.  It can be found here:  Phasors.

The other two documents are lectures I wrote several years ago for an advanced undergraduate course in Quantum Mechanics.  We will eventually cover most of this in either 214 or 213.  If the details are confusing, just read them to get the big picture of what is described. 

In the first of these lectures I discuss the state of Classical Mechanics and Electrodynamics at the point in time when troubling experiments began cropping up.  You can get that file here:  Introduction.

The second lecture discusses in detail several experiments that really caused physicists at the time to realized there was something seriously wrong with the classical picture of how the world worked.  These experiments and findings include the measurement of the temperature dependent black-body spectrum, the photoelectric effect, electron diffraction, and the observation that stable atoms exist, even when classical physics says they should not, and the measurement of characteristic atomic emission lines from different atoms.  You can find that here:  Experiments.

You can download the midterm exam here.

Answers to Chapters 35 and 36 were omitted in your textbook. They are available to download here.

Welcome

Please see the course description for an explanation of how this course works. It may seem complicated at first, but all the pieces do work together to enhance understanding. The course description also gives important details on our policies for missed exams, labs & quizzes. Also, please consult the course schedule to help you keep track of what is due when.

i>clickers

We will be using i>clickers in every lecture. You can use either the older v1 or the newer v2 i>clickers. If you have not already done so, please register your clicker by visiting https://my.physics.illinois.edu/iclicker/. The proven, educational benefit of using i>clickers depends on your active participation. Having another student answer questions using your clicker is considered cheating.

Excused Absences

The only course components eligible to be issued a grade of EX are discussions, labs and exams (except for the final). Please submit your excused absence no later than 10 business days from your absence via the Excused Absences application. For more information, please read the course description page.

Safety Announcements

Please read and become familiar with the Emergency Response Recommendations issued by the University.

For reference, Emergency Response Script read by your lecturer during the first lecture is also available.
