1. The problem statement, all variables and given/known data A clarinet behaves as an air column that is open at one end. For a particular fingering, the length of this air column is 24.6 cm. At 20°C, this fingering sounds the pitch "F" which is 349.2 Hz. During a concert, the breath of the musician raises the bore temperature to 27° C. A single percentage change in frequency would be noticeable to any listener. What would this new frequency be and would it be noticeable? 2. Relevant equations v = fλ v (speed of sound) = 331.4 m/s + (0.606 m/s/°C) T 3. The attempt at a solution I did this to find speed of sound in 20°C: v (speed of sound) = 331.4 m/s + (0.606 m/s/°C) (20°C) and I got 343.52 Hz, but it's 349.2 Hz in the clarinet (which is open at one end). I don't understand this concept; why is it 5.7 Hz higher? Also, in order to calculate the wavelength, I converted 24.6 cm into .246 m but I forgot what to do with this in the case that it is in a medium with an open end. I remember it's like λ/2 or something?
