A tube with a length L is closed at both ends and is filled with air. The wavelength of the fundamental mode of this tube is given by L*c, where c is a dimensionless constant. What is this constant, c, numerically? Also, the frequency of the first overture is how many times the fundamental frequency of this closed tube (numerically)?

start in the middle. the resonance to each end is 1/4 lambda, so the totalresonance is 1/2 lambda. C is 1/2

I tried it but the answer is still wrong =/. I'm not so sure if this has something to do with the other equation n = c/v but I doubt it.
