Don't measure from the nodes on the ends!

λ wavelength f frequency
(fixed at 60Hz)
T string tension v wave speed:
v = f · λ

  • For waves on a string:

    .
    Velocity eqn μ ("mu") linear density

    .

    .

  • Graph v vs. T using Kaleidagraph (not Excel!): Square root function!

  • From plot, get:

    • Vel

  • v vs. T
