Hi folks,
Today we took time to learn about natural frequency and resonance as well as a few more bits and pieces regarding waves and how they transfer energy. We also took quite a bit of time to relate all this information on waves to how they apply to sound. We watched some good/fun videos today so I've included them below.
Homework for next week is to:
Read the Sound chapter in the book. Pages 390 to 400 (We've been talking on and off about sound this entire unit. This chapter will help to solidify a lot of the concepts we've already been discussing.)
Do Review Questions on page 401 #'s 1 - 20.
