Homework Equations

I honestly do not know any relevant equations for this relationship.
Well except f=v/2l.

The Attempt at a Solution

The only thing I could assume that it was was some sort of error , but I cannot find much material on the topic , so I was hoping to get the opinion of a well experienced physicist.

for which you expect the graph of 1/f versus L to look how ?

(oh, and check the 2: that is for a closed pipe).
