Consider a pipe of length 80.0 cm open at both ends. what is the lowest frequency f of the sound wave produced when you blow into the pipe? express your answer in hertz.
To answer the problem we would be using the formula:v=λ*f where v=343 m/s length of standing wave λ=2*L=1.6m (since both of the ends are open), L=80.0cm =0.8m; but we are going to rearrange it. Therefore fundamental frequency is: f=v/λ = 343/(2*0.8) =214.375 Hz
