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.
