Size:  492.4 KBPls help me find the period of one oscillation.
    Ps. Its a displacement distance graph

    Well work out the wavelength - the distance taken to complete one whole cycle... i.e. the distance between 2 consecutive peaks
    work out the distance travelled between snapshots in the 0.4s - (by looking at the zero crossing points I think 0.5m)

    now that you know how far the wave progresses in 0.4 s and the wavelength you can calculate the period as the time required for the wave to progress by a distance equal to one wavelength.
How are you feeling about your exams?
