Wave Motion

  1. Apr 26, 2008 #1
    [SOLVED] Wave Motion

    1. The problem statement, all variables and given/known data
    A transverse wave on a string is described by the following wave function.

    y = (0.115 m) sin [(x/10 + 3t)]

    (a) Determine the transverse speed and acceleration at t = 0.240 s for the point on the string located at x = 1.70 m.
    (b) What are the wavelength, period, and speed of propagation of this wave?
    3. The attempt at a solution
    I have solved the whole problem up to part B) where it says what is the speed of propagation of this wave?
    I am not sure what is looking for me to find. I looked up wave propagation and it said, any of the ways in which a wave travels through a medium. I still can't figure out what I am trying to find, so if someone could explain what exactly it is looking for and how to go about it I would be grateful. Thanks

    The speed of a wave is simply [tex] v = \lambda f [/tex] or, equivalently, [tex] v = \omega/k [/tex]

    I got it, thanks.
