A student wants to determine the speed of sound at an elevation of one mile. To do this the student performs an experiment to determine the resonance frequencies of a tube that is closed at one end. The student takes measurements every day for a week and gets different results on different days.
1. Which of the following experiments would help the student determine the reason for the different results?
A. Repeating the experiment on several 10°C days and several 20°C days.
B. Repeating the experiment using a wider range of frequencies of sound.
C. Repeating the original experiment for an additional week.
D. Repeating the experiment using a longer tube.
