Giancoli Chapter 11 has been released! Waves and Vibrations are explained.
In this chapter you will find 3 hours and 4 minutes of videos giving answers to all your waves and vibrations physics questions (for the 6th Edition only, at the moment). Improve your grades and solve questions like a physicist with the techniques in these videos.
For the next little while I will be finishing the partially completed chapters, starting with chapter 7, then 9, and on to 18 and 19. After that I'll take a look at the chapter survey to see which one I should complete next.
