Unit 9 cont.


Today in class we started to learn about sound and the interaction between waves. On Thursday (yesterday), we talked about constructive and destructive interference, but today we learned about interaction between waves in a more visual way. We graphed the motion of waves for each second until the two waves had interacted and passed each other. When I was at the Kaupiko regatta this weekend, I sat on the beach with my crew, watching the waves. This got me thinking about physics. You could clearly see the waves breaking far off shore, and sometimes the waves would crash together and create a huge splash. Other times, one wave would surrender to the other and would go under, creating no turbulence above the water at all. Likely, when motion or sound waves have destructive interference, the waves would cancel each other out, resulting in a flat line. On the other hand, when motion or sound waves have constructive interference, the resulting wave would be larger than either of the original waves.
