Day 18: Speed of Sound
College-Prep Physics: Today we did the traditional speed of sound lab using Vernier microphones and Logger Pro. It turns out that our 4-sided meter sticks worked great as tubes. We stood them vertically on the floor so the floor acted as the reflecting surface. We got nice data:
We used the thermometer in the room and Hyperphysics to determine the actual speed of sound in the room. Most groups got with a few percent!
