Revision 120 as of 6:12PM, Feb 14, 2014

Welcome to Physics 5B, 2014!

  • Midterm is over. Check solutions (Homework+) and fill in the gaps of understanding, if possible. Much of it would continue to matter for the final exam, also, since we will continue doing waves, and interference, and so on, just with a different wave (light) for the next few lectures. Also, while you are at Homework+, remember to download Homework 5 if you did not pick up a hardcopy right after the exam.—6:09PM, Feb 14, 2014

  • Thanks to those students who participated in the device poll. Here is a summary.
    • ic: 21/98, sp: 84/98, tm: 85/98, lp: 67/98, tb: 14/98
    • sp|tm: 94/98, sp|tm|lp: 96/98, sp|tm|lp|tb: 96/98 (“|” means “or”)

Welcome to the second part of Physics 5!

In this course, we will continue the exploration of the introductory physics. We will start with the simple harmonic oscillator. Then, we will study waves in general. This will lead to geometric optics and related topics. Lastly, we will come back to fluids and statics. If we somehow run out of time, we might leave some topics like fluids for reading only. I like to go through the simple harmonic oscillator and waves, slowly but surely, so that we cover these supremely important topics well enough.
