For standing waves, wavelength lambda is twice the distance between nodes or anchor points.

The wavelength is going to be determined by it's length and how taut it is. The more you tighten it the higher the frequency the shorter the wave length. This is the principle by which all stringed musical instruments are tuned (guitar, violin, piano etc).
So you need to establish how you are going to tighten it.
Once you've done that you can pluck it continuously and measure the distance between the nodes (the points that are stationary). Average by the number of (nodes - 1) times 2 and you get an approximation of the wavelength
