  • Q2
    The diagram shows two original waves interfering with each other to produce a combined waveform. The two original waves, shown on the left side of the image, are:

    out of phase with each other (destructive)
    amplifying each other
    in phase with each other (constructive)

  • Q10
    When the source of a wave is moving relative to an observer of the wave, which of the following is true?
    Question Image
    observers behind the wave observe lower wavelengths and higher frequency
    observers both ahead of and behind the wave notice an increase in frequency
    observers ahead of the wave observe an apparent increase in wave frequency
    observers in all directions notice a decrease in wave frequency
