Homework Statement

A 3.0 organ pipe is open at both ends. The velocity of sound is 331 m/s. What is the wavelength of the lowest frequency?

Homework Equations

am i missing something...i need a lil help here!

The Attempt at a Solution

wavelength=2L/n fn=V/wavelength(n)=n(V/2L)=nf1
n(331)/(2)(3.0) ?
