The clarinet's lowest note is D3, 147 Hz. What is its effective length, that is, the length of an idealized closed pipe that has this frequency for its first mode? Explain why this is less than the actual length of the instrument?

clarinet closed? No way. It is closed at one end, open at the other. It is .25 wavelength long, ignoring things like temperature, diameter which changes the speed of sound.

147*4L=343
solve for L.
