  1. What does incomplete mean?

  2. My book has an example or whatever and it says word for word: If the opposite pulses have unequal amplitudes, cancellation is incomplete.

    my answer book may have a typo because my choices are:

    A)equal amplitudes
    B)different energies
    C)equal pulses
    D)equal displacements

    I think A should read UNequal amplitudes and then I would choose that. I am reading the questions carefully that's how I figure out how to go about solving them and where to look in my book. If A is not a typo, is that still the answer? incomplete means not finished. I know what they mean in my book I hope you knew that already

    For incomplete cancellation to occur, opposite pulses must have equal amplitudes different energies equal pulses equal displacements it seems like none of these are quite right but would different energies be the closest.
