Standing Wave harmonics

  1. Nov 24, 2009 #1
    Why does half a wave length and not a full wave length constitute the first harmonic?



    v=[tex]\lambda[/tex]f



    because a standing waves can be made with two half waves travelling in opposite directions?

    Here is a good resource on http://www.physicsclassroom.com/Class/waves/U10L4e.cfm" [Broken].

    Basically you are right, but your terminology isn't quite correct. The wavelength is the length up and back the string, so [itex]\lambda=2L\rightarrow L=\frac{1}{2}\lambda[/itex].
