For incomplete cancellation to occur, opposite pulses must have.

equal displacements

  • physics -

    What does incomplete mean?

  • DrBob222 -

    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
