Homework Statement
A closed air column is 60.0cm long. Calculate the frequency of the forks that will cause resonance at:
a) the first resonant length
b) the second resonant length
Note that the speed of sound is 344m/s.
Homework Equations
Ln = (2n - 1) * [tex]\lambda[/tex] / 4
fn = (2n - 1)f1, where f1 = V/4L and 4L = [tex]\lambda[/tex]
The Attempt at a Solution
I cannot figure out what the actual magnitude of the resonant length is, and don't know how to begin solving the problem.
Thanks.
