Period of a wave

  1. Feb 27, 2008 #1
    1. The problem statement, all variables and given/known data
    A wave traveling in the positive x direction with a frequency of 19.0 Hz

    The full amplitude of the wave is 0.18 m and the wavelength is 0.20 m

    What is the period and speed of the wave?
    2. Relevant equations

    speed=(frequency)*(wavelength)
    Frequency=1/period

    3. The attempt at a solution

    I figured the speed by doing 19*0.20 which equaled to 3.8 m/s
    For the period, i just did 1/19 and got 0.0526 s but am not too sure about this answer. Please direct me! Thanks!

    Your answer is right. 1/19 would be the Period.
