A long-wavelength wave and a short-wavelength wave both move along the same rope. Which wave has the higher frequency, and which wave carries more energy, assuming their amplitudes are the same?
 
  A) The short-wavelength wave has the higher frequency, but the two waves carry the same amounts of energy.
  B) The long-wavelength wave has the higher frequency and but the short-wavelength wave carries more energy.
  C) The long-wavelength wave has the higher frequency and carries more energy.
  D) The short-wavelength wave has the higher frequency and but the long-wavelength wave carries more energy.
  E) The short-wavelength wave has the higher frequency and carries more energy.
 
  E) no disturbance, because they cancel.
