1. The problem statement, all variables and given/known data The second overtune for a pipe, open at both ends is 2000 Hz, the speed of the sound is 343 m/s. What is the length of the pipe? 2. Relevant equations • λ = v/f 3. The attempt at a solution λ = v/f = (340 m/s)/(2000 Hz) = 0.17 m don't know if this is correct. Thanks in advanced.
