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.
