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.

You found the wavelength of the sound. How is that related to the length of the pipe?
