1. The problem statement, all variables and given/known data A 5.00-m, 0.732-kg wire is used to support two uniform 235-N posts of equal length (see figure). Assume that the wire is essentially horizontal and that the speed of sound is 344 m/s. A strong wind is blowing, causing the wire to vibrate in its 7th overtone. What are the frequency and wavelength of the sound this wire produces? 2. Relevant equations at 7th overtone: L= 8(lamda/2) 3. The attempt at a solution lamda = (2/8)L = (2/8)(5) = (5/4) m Is my wavelength correct? I'm not sure of which equation to use to find the frequency.
