Summary: My LO addressed the similarities and difference between waves on a string and sound wave. The sound wave speed in different mediums is discussed. In addition, it talked about the wave intensity and the relationship between distance and intensity. The questions are word problems that require calculation. I choose to use Prezi for my presentation.
