1. The instructor informs Carey that his determination of the wave speed is lower then the actual value. The instructor suggests that he try the first overtone. Why would the instructor suggest this and how would it change the measurements and outcome?

3. In the teacher's response they mention, "the natural frequency of the pipe". What does the teacher mean by this statement?
