Mechanical Waves

Because I will be out next Wednesday, I have had to rearrange some things, and that means today we are taking a little break from SHM to talk about mechanical waves. We will go back to SHM on Monday/Tuesday with another lab, so bring your lab notebook next time. I will also be checking your Period of a Spring Lab on Monday/Tuesday.

Here are the notes for today:



Here is a website with animations of the different kids of mechanical waves:
