    A question (part A) asks me to calculate the speed of a stationary wave on a string (provding wavelength and frequency), then it asks me 'Explain what is meant by the speed calculated in part A.' Can anyone answer this?

    Yes, i know that, that is why I asked.
    The question is from a past examination (october 2004), yet they give me the frequency of the stationary wave and the wavelength and the speed is to be calculated.

    I have attached the question

    the standing wave is formed by a reflected wave interfering with the incident wave. e.g. if the incident wave travels right, and is reflected to the left, it will interfere.

    the speed refers to the speed of the incident or reflected wave, and is just v=f.lambda
