so we used an equation in class to basically describe the relationship between some quantities of a vibrating string held fixed at both ends. and i noticed (just now...) that this was.. well.. i don't want to say that it's 'wrong' yet but, the expression does not make sense to me; and just to make sure that i haven't gone dumb or anything i checked online for the expression of the same scenario and they had the same equation that i derived.
here is a picture of the page in my thermo book using the equation (circled in green) that i disagree with.

even at the bottom of the page with the diagram, λ3 is NOT (2/3)L it should be 1.5L or, (3/2)L. basically my question is... why in the world is the 2 and the n inverted??
thanks
