The Attempt at a Solution
So, I got (A), which is the answer key is correct, but I'm not sure whether my reasoning is right or not. Would this be considered a closed-end air column question? Anyways, according to the length-wavelength relationships for the harmonics (which can be seen here: http://www.physicsclassroom.com/class/sound/Lesson-5/Closed-End-Air-Columns), an increase
in length will produce an increase in wavelength. Since both columns have the same height of water in them, the speed of sound through both should be the same, right? This means that the taller column will have a lower frequency than the shorter column, which will need a higher frequency to compensate for the shorter height, making the answer (A) f_1. Is my reasoning correct?
