Homework Help: Calculating the frequency of a wave

  1. Mar 28, 2009 #1
    1. The problem statement, all variables and given/known data
    A snapshot graph of a travelling wave is shown. The wave is travelling to the right at 44.0 m/s. the maximum displacement is 18.0 cm and the total distance travelled by the wave is 28.0 m
    What is the frequency?

    2. Relevant equations
    3. The attempt at a solution
    total distance traveled/ # ticks = 28 m/10 = 2.8m/tick

    There are 7 ticks in one wavelength

    7*2.8 = 19.6 m

    Do a recount. Once you find the wavelength, how do you calculate the frequency?

    now it works, thanks :)
    ** 6 ticks to a wavelength, making it 16.8 m

    and then frequency = c/lamba
    = 44/16.8
    = 2.6 Hz
