    1. The problem statement, all variables and given/known data
    You send a pulse down a string that is attached to second string of unknown properties. the pulse returns to inverted and with a smaller amplitude.
    A)is the speed slower or faster in the second string
    B)is the wavelength smaller or larger in the second string
    2. Relevant equations

    3. The attempt at a solution
    A)it is slower because it came back inverted and with a smaller amplitude
    B)the wavelength stays the same

    The wavelength is not the same. You already know that the speed changes. What else could be constant, and how will that affect the wavelength?
