Standing wave on a metal rod

  1. Nov 1, 2015 #1
    1. The problem statement, all variables and given/known data
    An otherwise free metal rod of length L = 67-cm is clamped at a point L/18 from one end. A standing wave is set up on the rod. What is its longest possible wavelength?

    3. The attempt at a solution

    where do I go wrong?
    thanks

    Consider where the nodes and anti-nodes are.

    The clamped point will be a node of the standing wave. The free end is an antinode. For the longest wave, the difference between these two points will be 1/4 of the wavelength !!
