Homework Help: Mechanical Oscillator: finding frequency and wavelength of transverse wave

  1. Aug 10, 2011 #1
    A mechanical oscillator connected to the end of a stretched string creates a transverse displacement of the end that is given by ξ = 0.009 sin(22.8 t), where ξ is in meters, t is in seconds (and the argument of the sin function is in radians). The tension in the string is 11.08, and the string has a linear mass density of 11 grams/m. Find the frequency ν of the transverse waves, in units of Hz. Also Find the wavelength of the transverse waves, in units of m.

    I found the propagation velocity (Cw). I believe I need to use the equation [itex]\lambda[/itex]=[itex]\frac{Cw}{\upsilon}[/itex]. I am not sure what other equation(s) to use.

    The frequency of a wave is the frequency of the thing causing the wave - the oscillator connected. That ξ expression should enable you to work that out.
