## Main Question or Discussion Point

I'm looking for a formula to calculate the resonant frequency of a capped cylinder. I have found a link to a formula but was surprised to see that cylinder radius is not taken into account when making the calculation.

It was my understanding that the larger the radius of a cylinder the lower the note produced, is that correct?

How dose cylinder radius relate to the note produced eg if I had five cylinders of equal length but each one being twice the radius of the other what effect would this have on the sound produced?

Here is a link to the formula I mentioned
